       lynx  - a general purpose distributed information browser for the World
       Wide Web

       lynx [options] [optional paths or URLs]

       lynx [options] [path or URL] -get_data

       Use "lynx -help" to display a complete list of current options.

       Lynx is a fully-featured World Wide Web (WWW) client for users  running
       cursor-addressable,   character-cell   display   devices  (e.g.,  vt100
       terminals, vt100 emulators running on Windows 95/NT/XP/7/8 or any POSIX
       platform,  or  any  other  "curses-oriented" display).  It will display
       hypertext markup language (HTML) documents containing  links  to  files
       residing  on  the  local  system,  as  well as files residing on remote
       systems running Gopher, HTTP, FTP, WAIS,  and  NNTP  servers.   Current
       versions  of Lynx run on Unix, VMS, Windows 95/NT/XP/7/8, DOS DJGPP and

       Lynx can be used to access information on the World  Wide  Web,  or  to
       build  information  systems  intended  primarily for local access.  For
       example, Lynx has been used to build several  Campus  Wide  Information
       Systems  (CWIS).   In  addition,  Lynx  can  be  used  to build systems
       isolated within a single LAN.

       At start up, Lynx will load any local file or remote URL  specified  at
       the  command line.  For help with URLs, press "?"  or "H" while running
       Lynx.  Then follow the link titled, "Help on URLs."

       If more than one local file or remote URL  is  listed  on  the  command
       line,  Lynx  will  open  only the last interactively.  All of the names
       (local files and remote URLs) are added to the G)oto history.

       Lynx uses only long option names.  Option names can begin  with  double
       dash  "--"  as well, underscores and dashes can be intermixed in option
       names (in the reference below, options are  shown  with  one  dash  "-"
       before them, and with underscores "_").

       Lynx  provides many command-line options.  Some options require a value
       (string, number or keyword).  These are noted in the  reference  below.
       The  other  options set boolean values in the program.  There are three
       types of boolean options: set, unset and toggle.  If no option value is
       given, these have the obvious meaning: set (to true), unset (to false),
       or toggle (between true/false).  For any of these,  an  explicit  value
       can  be  given  in  different  forms  to  allow  for  operating  system
       constraints, e.g.,


       Lynx recognizes "1", "+", "on" and "true" for  true  values,  and  "0",
       "-",  "off"  and  "false"  for  false  values.  Other option-values are

       The default boolean, number and string option values that are  compiled
       into  Lynx  are  displayed  in the help-message provided by lynx -help.
       Some of those may differ according to how Lynx was built; see the  help
       message  itself for these values.  The -help option is processed in the
       third pass of options-processing, so any option which sets a value,  as
       well as runtime configuration values are reflected in the help-message.

       -      If  the  argument  is only "-", then Lynx expects to receive the
              arguments from the standard input.  This is  to  allow  for  the
              potentially  very  long command line that can be associated with
              the -get_data or -post_data arguments (see below).  It can  also
              be  used  to  avoid having sensitive information in the invoking
              command line (which would be visible to other processes on  most
              systems), especially when the -auth or -pauth options are used.

              accept all cookies.

              apply    restrictions    for   anonymous   account,   see   also

              charset for documents that do not specify it.

              charset assumed for local files, i.e., files which Lynx  creates
              such as internal pages for the options menu.

              use this instead of unrecognized charsets.

              set  authorization  ID  and  password for protected documents at
              startup.  Be sure to protect any script  files  which  use  this

       -base  prepend  a request URL comment and BASE tag to text/html outputs
              for -source dumps.

              specify a local bibp server (default http://bibhost/).

       -blink forces high intensity  background  colors  for  color  mode,  if
              available  and  supported  by the terminal.  This applies to the
              slang library (for a few terminal emulators),  or  to  OS/2  EMX
              with ncurses.

       -book  use  the bookmark page as the startfile.  The default or command
              line startfile is still set for the  Main  screen  command,  and
              will be used if the bookmark page is unavailable or blank.

              toggles  scanning  of  news  articles for buried references, and
              converts them to news  links.   Not  recommended  because  email
              addresses  enclosed in angle brackets will be converted to false
              news links, and uuencoded messages can be trashed.

              set the NUMBER of documents cached in memory.   The  default  is

       -case  enable case-sensitive string searching.

              Toggle center alignment in HTML TABLE.

              specifies  a  Lynx  configuration  file  other  than the default

       -child exit on left-arrow in startfile, and disable save  to  disk  and
              associated print/mail options.

              exit  on  left-arrow  in  startfile,  but allow save to disk and
              associated print/mail options.

              write  keystroke  commands  and  related  information   to   the
              specified file.

              read  keystroke  commands  from the specified file.  You can use
              the data written using the -cmd_log option.   Lynx  will  ignore
              other  information which the command-logging may have written to
              the logfile.  Each line of the command script contains either  a
              comment beginning with "#", or a keyword:

                 causes   the   script  to  stop,  and  forces  Lynx  to  exit

                 the character value, in printable  form.   Cursor  and  other
                 special   keys  are  given  as  names,  e.g.,  "Down  Arrow".
                 Printable 7-bit ASCII codes are given as-is, and  hexadecimal
                 values represent other 8-bit codes.

                 followed  by a "name=value" allows one to override values set
                 in the lynx.cfg or .lynxrc files.  Lynx  tries  the  cfg-file
                 setting first.

              toggles collapsing of BR tags.

       -color forces  color  mode  on,  if  available.   Default color control
              sequences which work for many terminal types are assumed if  the
              terminal  capability  description does not specify how to handle
              color.  Lynx needs to be compiled with  the  slang  library  for
              this flag, it is equivalent to setting the COLORTERM environment
              variable.  (If color support is instead  provided  by  a  color-
              capable  curses  library like ncurses, Lynx relies completely on
              the terminal description to  determine  whether  color  mode  is
              possible,  and this flag is not needed and thus unavailable.)  A
              saved show_color=always setting  found  in  a  .lynxrc  file  at
              startup  has the same effect.  A saved show_color=never found in
              .lynxrc on startup is overridden by this flag.

              Sets the connection timeout, where N is given in seconds.

              specifies a file to use to read cookies.  If none is  specified,
              the  default  value  is  ~/.lynx_cookies  for  most systems, but
              ~/cookies for MS-DOS.

              specifies a file to use to store cookies.  If none is specified,
              the value given by -cookie_file is used.

              toggles handling of Set-Cookie headers.

       -core  toggles forced core dumps on fatal errors.  Turn this option off
              to ask Lynx to force a core dump if a fatal error occurs.

       -crawl with -traversal, output each page to a file.  with -dump, format
              output as with -traversal, but to the standard output.

              toggles   the   use  of  curses  "pad"  feature  which  supports
              left/right scrolling of the display.  The  feature  is  normally
              available  for curses configurations, but inactive.  To activate
              it, use  the  "|"  character  or  the  LINEWRAP_TOGGLE  command.
              Toggling this option makes the feature altogether unavailable.

              separate incremental display stages with MessageSecs delay

              toggles  the default-colors feature which is normally set in the
              lynx.cfg file.

       -delay add DebugSecs delay after each progress-message

              set the display variable for X rexec-ed programs.

              set the charset for the terminal output.

              inhibit wrapping of text when  -dump'ing  and  -crawl'ing,  mark
              wrapped lines of <pre> in interactive session.

       -dump  dumps  the  formatted  output  of  the default document or those
              specified on  the  command  line  to  standard  output.   Unlike
              interactive mode, all documents are processed.  This can be used
              in the following way:

                  lynx -dump

              Files specified on the command line are  formatted  as  HTML  if
              their  names  end  with one of the standard web suffixes such as
              ".htm" or ".html".  Use the -force_html option to  format  files
              whose names do not follow this convention.

              enable  external  editing, using the specified EDITOR.  (vi, ed,
              emacs, etc.)

              enable emacs-like key movement.

              toggles compatibility with  communication  programs'  scrollback
              keys (may be incompatible with some curses packages).

              define a file where Lynx will report HTTP access codes.

       -exec  enable local program execution (normally not configured).

              include all versions of files in local VMS directory listings.

              toggle memory leak-checking.  Normally this is not compiled-into
              your executable, but when it  is,  it  can  be  disabled  for  a

              force  HREF-less "A" elements to be empty (close them as soon as
              they are seen).

              forces the first document to be interpreted as HTML.

              This is most useful  when  processing  files  specified  on  the
              command line which have an unrecognized suffix (or the suffix is
              associated with a non-HTML type, such as ".txt" for  plain  text

              Lynx recognizes these file suffixes as HTML:

                  ".sht", and

              toggles forcing of the secure flag for SSL cookies.

              toggles whether the Options Menu is key-based or form-based.

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

              properly  formatted  data  for  a  get form are read in from the
              standard input and passed to the form.  Input is terminated by a
              line that starts with "---".

              Lynx  issues  an  HTTP  GET, sending the form to the path or URL
              given on the command-line and prints the response of the server.
              If  no  path  or URL is given, Lynx sends the form to the start-

       -head  send a HEAD request for the mime headers.

       -help  print the Lynx command syntax usage message, and exit.

              control the display of hidden links.

                 hidden links show up as bracketed numbers  and  are  numbered
                 together with other links in the sequence of their occurrence
                 in the document.

                 hidden links are shown only on  L)ist  screens  and  listings
                 generated  by  -dump  or  from  the  P)rint  menu, but appear
                 separately at the end of those lists.  This  is  the  default

                 hidden links do not appear even in listings.

              toggles use of ">" or "-->" as a terminator for comments.

              set homepage separate from start page.

              toggles inclusion of links for all images.

              set the default index file to the specified URL.

       -ismap toggles  inclusion  of  ISMAP  links  when  client-side MAPs are

              do justification of text.

              starting count for lnk#.dat files produced by -crawl.

              for -dump, show URL-encoded links decoded.

              for -dump, show the links inline with the text.

              for -dump, show only the list of links.

              disable URLs that point to remote hosts.

              enable local program execution from local files  only  (if  Lynx
              was compiled with local execution enabled).

              specify   filename   containing  color-style  information.   The
              default is lynx.lss.  If you give an empty filename, Lynx uses a
              built-in  monochrome  scheme  which imitates the non-color-style

              prints the MIME header of a  fetched  document  along  with  its

              toggles minimal versus valid comment parsing.

              toggles nested-tables logic (for debugging).

              number of articles in chunked news listings.

              maximum news articles in listings before chunking.

              disable bold video-attribute.

              disable directory browsing.

       -nocc  disable Cc: prompts for self copies of mailings.  Note that this
              does not disable any CCs which are incorporated within a  mailto
              URL or form ACTION.

              force  color  mode off, overriding terminal capabilities and any
              -color flags, COLORTERM variable, and saved .lynxrc settings.

              disable local program execution.  (DEFAULT)

              disable transmissions of Referer headers for file URLs.

              disable the link list feature in dumps.

       -nolog disable mailing of error messages to document owners.

              disable left/right margins in the default style sheet.

              disable -more- string in statusline messages.

              This flag is not available on all  systems,  Lynx  needs  to  be
              compiled  with  HAVE_SIGACTION defined.  If available, this flag
              may cause Lynx to react more immediately to window changes  when
              run within an xterm.

              disable    link-    and    field-numbering.     This   overrides
              -number_fields and -number_links.

              disable forced pauses for statusline messages.

              disable most print functions.

              prevents automatic redirection and prints a message with a  link
              to the new URL.

              disable transmissions of Referer headers.

              disable reverse video-attribute.

              disable SOCKS proxy usage by a SOCKSified Lynx.

              disable the retrieval status messages.

              disable title and blank line from top of page.

              disable underline video-attribute.

              force numbering of links as well as form input fields

              force numbering of links.

              toggles display partial pages while loading.

              partial-display logic

              toggles passive ftp connections.

              set authorization ID and password for a protected  proxy  server
              at  startup.  Be sure to protect any script files which use this

       -popup toggles handling  of  single-choice  SELECT  options  via  popup
              windows or as lists of radio buttons.

              properly  formatted  data  for  a post form are read in from the
              standard input and passed to the form.  Input is terminated by a
              line that starts with "---".

              Lynx  issues  an  HTTP POST, sending the form to the path or URL
              given on the command-line and prints the response of the server.
              If  no  path  or URL is given, Lynx sends the form to the start-

              show HTML  source  preparsed  and  reformatted  when  used  with
              -source or in source view.

              show HTML source view with lexical elements and tags in color.

       -print enable print functions.  (default)

              toggles pseudo-ALTs for inline images with no ALT string.

       -raw   toggles  default  setting of 8-bit character translations or CJK
              mode for the startup character set.

       -realm restricts access to URLs in the starting realm.

              Sets the read-timeout, where N is given in seconds.

              flushes the cache on a proxy server  (only  the  first  document
              given on the command-line is affected).

              allows  a  list  of services to be disabled selectively.  Dashes
              and  underscores  in  option  names  can  be  intermixed.    The
              following list is printed if no options are specified.

                 restricts all options listed below.

                 disallow changing the location of the bookmark file.

                 disallow execution links via the bookmark file.

                 disallow  changing the eXecute permission on files (but still
                 allow it for  directories)  when  local  file  management  is

                 same  as  command  line  option -anonymous.  Disables default
                 services for anonymous users.  Set to all restricted,  except
                 for:  inside_telnet, outside_telnet, inside_ftp, outside_ftp,

                 telnet_port, jump, mail, print, exec, and goto.  The settings
                 for these,  as  well  as  additional  goto  restrictions  for
                 specific  URL schemes that are also applied, are derived from
                 definitions within userdefs.h.

                 disallow local file management.

                 disallow saving to disk in the download and print menus.

                 disallow access to, or creation of, hidden (dot) files.

                 disallow some downloaders in  the  download  menu  (does  not
                 imply disk_save restriction).

                 disallow external editing.

                 disable execution scripts.

                 disallow the user from changing the local execution option.

                 disallow  some  "EXTERNAL" configuration lines if support for
                 passing  URLs  to  external  applications  (with  the  EXTERN
                 command) is compiled in.

                 disallow  using  G)oto,  served  links or bookmarks for file:

                 disable the "g" (goto) command.

                 disallow ftps for people coming from inside your domain (utmp
                 required for selectivity).

                 disallow  USENET  news  posting for people coming from inside
                 your domain (utmp required for selectivity).

                 disallow USENET News posting.

                 disallow saving options in .lynxrc.

                 disallow ftps for people  coming  from  outside  your  domain
                 (utmp required for selectivity).

                 disallow  USENET  news  reading and posting for people coming
                 from outside your domain  (utmp  required  for  selectivity).
                 This  restriction  applies to "news", "nntp", "newspost", and
                 "newsreply"  URLs,  but  not  to  "snews",  "snewspost",   or
                 "snewsreply" in case they are supported.

                 disallow  rlogins  for people coming from outside your domain
                 (utmp required for selectivity).

                 disallow telnets for people coming from outside  your  domain
                 (utmp required for selectivity).

                 disallow most print options.

                 disallow shell escapes and lynxexec or lynxprog G)oto's.

                 disallow Unix Control-Z suspends with escape to shell.

                 disallow specifying a port in telnet G)oto's.

                 disallow modifications of the User-Agent header.

              toggles  forced  resubmissions  (no-cache)  of forms with method
              POST when the  documents  they  returned  are  sought  with  the
              PREV_DOC command or from the History List.

              disable recognition of rlogin commands.

              toggles showing scrollbar.

              toggles showing arrows at ends of the scrollbar.

              require .www_browsable files to browse directories.

              resumes from specified file on startup and saves session to that
              file on exit.

              show very long URLs in the status line with "..."  to  represent
              the portion which cannot be displayed.  The beginning and end of
              the URL are displayed, rather than suppressing the end.

              Print the configuration settings, e.g., as read from "lynx.cfg",
              and exit.

              If  enabled  the  cursor  will  not  be hidden in the right hand
              corner but will instead  be  positioned  at  the  start  of  the
              currently selected link.  Show cursor is the default for systems
              without FANCY_CURSES capabilities.   The  default  configuration
              can  be  changed  in  userdefs.h  or lynx.cfg.  The command line
              switch toggles the default.

              If enabled the transfer  rate  is  shown  in  bytes/second.   If
              disabled,  no  transfer  rate  is  shown.   Use  lynx.cfg or the
              options menu to select KB/second and/or ETA.

              (Via which) SOCKS5 proxy to connect.  This controls the  builtin
              SOCKS5  support,  and  is  therefore  unrelated  to  the  option

              toggles emulation of the  old  Netscape  and  Mosaic  bug  which
              treated ">" as a co-terminator for double-quotes and tags.

              works  the  same  as  dump  but  outputs  HTML source instead of
              formatted text.  For example

                  lynx -source . >foo.html

              generates  HTML  source  listing  the  files  in   the   current
              directory.   Each  file  is  marked  by  an HREF relative to the
              parent directory.  Add a  trailing  slash  to  make  the  HREF's
              relative to the current directory:

                  lynx -source ./ >foo.html

              disable SIGINT cleanup handler

              allow non-http startfile and homepage with -validate.

              When  dumping  a  document using -dump or -source, Lynx normally
              does not display alert (error) messages  that  you  see  on  the
              screen  in the status line.  Use the -stderr option to tell Lynx
              to write these messages to the standard error.

       -stdin read the startfile from standard input (UNIX only).

              information for syslog call.

              log requested URLs with syslog.

              initialize parser, using Tag Soup DTD rather than SortaSGML.

              disable recognition of telnet commands.

              tell Lynx what terminal type to assume it is talking to.   (This
              may  be  useful  for  remote  execution, when, for example, Lynx
              connects to a remote TCP/IP port that starts a script  that,  in
              turn, starts another Lynx process.)

              For  win32,  sets  the network read-timeout, where N is given in

       -tlog  toggles between using a Lynx Trace  Log  and  stderr  for  trace
              output from the session.

       -tna   turns on "Textfields Need Activation" mode.

       -trace turns  on  Lynx trace mode.  Destination of trace output depends
              on -tlog.

              turn on optional traces, which may result in  very  large  trace
              files.  Logically OR the values to combine options:

              1  SGML character parsing states

              2  color-style

              4  TRST (table layout)

              8  configuration  (lynx.cfg,  .lynxrc, .lynx-keymaps, mime.types
                 and mailcap contents)

                 detailed URL parsing

              traverse all http links derived from startfile.  When used  with
              -crawl,  each link that begins with the same string as startfile
              is output to a file, intended for indexing.

              See CRAWL.announce for more information.

              toggles trimming of trailing blank lines as well as the  related
              trimming of blank lines while collapsing BR tags.

              trim input text/textarea fields in forms.

              toggles use of underline/bold attribute for links.

              toggles use of _underline_ format in dumps.

              check  for duplicate link numbers in each page and corresponding
              lists, and reuse the original link number.

              enables updating the title in terminal emulators.  Use  only  if
              your terminal emulator supports that escape code.  Has no effect
              when used with -notitle.

              turn on mouse support, if available.  Clicking  the  left  mouse
              button  on a link traverses it.  Clicking the right mouse button
              pops back.  Click on the top line to scroll up.   Click  on  the
              bottom  line to scroll down.  The first few positions in the top
              and bottom line may invoke additional functions.  Lynx  must  be
              compiled  with  ncurses  or  slang  to support this feature.  If
              ncurses is used, clicking the middle  mouse  button  pops  up  a
              simple  menu.  Mouse clicks may only work reliably while Lynx is
              idle waiting for input.

              set alternate Lynx User-Agent header.

              accept only  http  URLs  (for  validation).   Complete  security
              restrictions also are implemented.

              toggle  [LINK],  [IMAGE] and [INLINE] comments with filenames of
              these images.

              print version information, and exit.

              enable vi-like key movement.

              enable Waterloo tcp/ip packet debug (print to  watt  debugfile).
              This  applies  only  to  DOS  versions  compiled  with WATTCP or

              number of columns for formatting of dumps, default is 80.   This
              is  limited  by  the  number of columns that Lynx could display,
              typically 1024 (the MAX_LINE symbol).

              emit backspaces in output if -dump'ing or -crawl'ing  (like  man

              tells Lynx that it can ignore certain tags which have no content
              in an XHTML 1.0 document.  For example "<p/>" will be discarded.

       More than one key can be mapped to a given command.  Here are  some  of
       the most useful:

       o   Use Up arrow and Down arrow to scroll through hypertext links.

       o   Right arrow or Return will follow a highlighted hypertext link.

       o   Left Arrow or "u" will retreat from a link.

       o   Type "H", "?", or F1 for online help and descriptions of key-stroke

       o   Type "k" or "K" for  a  list  of  the  current  key-stroke  command

           If  the same command is mapped to the same letter differing only by
           upper/lowercase only the lowercase mapping is shown.

       o   Type Delete to view history list.

       In addition to various "standard" environment variables such  as  HOME,
       PATH,  USER,  DISPLAY, TMPDIR, etc, Lynx utilizes several Lynx-specific
       environment variables, if they exist.

       Others may be created or modified by Lynx to pass data to  an  external
       program, or for other reasons.  These are listed separately below.

       See  also  the  sections  on  SIMULATED CGI SUPPORT and NATIVE LANGUAGE
       SUPPORT, below.

       Note:  Not all environment variables apply to all  types  of  platforms
       supported  by  Lynx, though most do.  Feedback on platform dependencies
       is solicited.

       Environment Variables Used By Lynx:

       COLORTERM           If set, color capability for the terminal is forced
                           on  at  startup time.  The actual value assigned to
                           the variable is ignored.   This  variable  is  only
                           meaningful  if  Lynx  was  built  using  the  slang
                           screen-handling library.

       LYNX_CFG            This variable, if set, will  override  the  default
                           location  and name of the global configuration file
                           (normally,  lynx.cfg)  that  was  defined  by   the
                           LYNX_CFG_FILE  constant  in  the  userdefs.h  file,
                           during installation.

                           See the userdefs.h file for more information.

       LYNX_CFG_PATH       If set, this  variable  overrides  the  compiled-in
                           search-list   of   directories  used  to  find  the
                           configuration files, e.g., lynx.cfg  and  lynx.lss.
                           The list is delimited with ":" (or ";" for Windows)
                           like the PATH environment variable.

       LYNX_HELPFILE       If set, this variable overrides the compiled-in URL
                           and configuration file URL for the Lynx help file.

       LYNX_LOCALEDIR      If  set,  this  variable  overrides the compiled-in
                           location of the  locale  directory  which  contains
                           native language (NLS) message text.

       LYNX_LSS            This  variable,  if  set, specifies the location of
                           the  default  Lynx  character  style  sheet   file.
                           [Currently  only meaningful if Lynx was built using
                           curses color style support.]

       LYNX_SAVE_SPACE     This variable, if set, will  override  the  default
                           path prefix for files saved to disk that is defined
                           in the lynx.cfg SAVE_SPACE: statement.

                           See the lynx.cfg file for more information.

       LYNX_TEMP_SPACE     This variable, if set, will  override  the  default
                           path  prefix  for  temporary files that was defined
                           during installation, as well as any value that  may
                           be assigned to the TMPDIR variable.

       MAIL                This variable specifies the default inbox Lynx will
                           check for new mail, if such checking is enabled  in
                           the lynx.cfg file.

       NEWS_ORGANIZATION   This  variable, if set, provides the string used in
                           the Organization: header of USENET  news  postings.
                           It  will  override  the setting of the ORGANIZATION
                           environment variable, if it is also  set  (and,  on
                           UNIX, the contents of an /etc/organization file, if

       NNTPSERVER          If set, this variable specifies  the  default  NNTP
                           server  that  will  be used for USENET news reading
                           and posting with Lynx, via news: URL's.

       ORGANIZATION        This variable, if set, provides the string used  in
                           the  Organization:  header of USENET news postings.
                           On UNIX,  it  will  override  the  contents  of  an
                           /etc/organization file, if present.

       PROTOCOL_proxy      Lynx supports the use of proxy servers that can act
                           as firewall gateways and caching servers.  They are
                           preferable   to  the  older  gateway  servers  (see
                           WWW_access_GATEWAY, below).

                           Each protocol used by  Lynx,  (http,  ftp,  gopher,
                           etc),   can   be   mapped   separately  by  setting
                           environment variables of the  form  PROTOCOL_proxy.
                           Protocols are indicated in a URI by the name before
                           ":", e.g., "http" in "http://some.server.dom:port/"
                           for HTML.

                           Depending   on   your   system   configuration  and
                           supported  protocols,  the  environment   variables
                           recognized by lynx may include


                           See  Lynx  Users  Guide  for additional details and

       SSL_CERT_DIR        Set   to   the   directory    containing    trusted

       SSL_CERT_FILE       Set  to the full path and filename for your file of
                           trusted certificates.

       WWW_access_GATEWAY  Lynx still supports use of  gateway  servers,  with
                           the   servers  specified  via  "WWW_access_GATEWAY"
                           variables (where "access" is lower case and can  be
                           "http",  "ftp",  "gopher" or "wais").  However most
                           gateway servers have been discontinued.  Note  that
                           you do not include a terminal "/" for gateways, but
                           do  for   proxies   specified   by   PROTOCOL_proxy
                           environment variables.

                           See Lynx Users Guide for details.

       WWW_HOME            This  variable,  if  set, will override the default
                           startup  URL  specified  in   any   of   the   Lynx
                           configuration files.

       Environment Variables Set or Modified By Lynx:

       LYNX_PRINT_DATE     This  variable is set by the Lynx p(rint) function,
                           to  the  Date:  string  seen  in   the   document's
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           Date" under VMS.

       LYNX_PRINT_LASTMOD  This variable is set by the Lynx p(rint)  function,
                           to  the  Last  Mod:  string  seen in the document's
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           LastMod" under VMS.

       LYNX_PRINT_TITLE    This  variable is set by the Lynx p(rint) function,
                           to the Linkname:  string  seen  in  the  document's
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           Title" under VMS.

       LYNX_PRINT_URL      This variable is set by the Lynx p(rint)  function,
                           to   the   URL:   string  seen  in  the  document's
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           URL" under VMS.

       LYNX_TRACE          If set, causes Lynx to write a trace file as if the
                           -trace option were supplied.

       LYNX_TRACE_FILE     If set, overrides the compiled-in name of the trace
                           file,  which  is  either Lynx.trace or LY-TRACE.LOG
                           (the latter on  the  DOS/Windows  platforms).   The
                           trace  file  is in either case relative to the home

       LYNX_VERSION        This variable is always set by  Lynx,  and  may  be
                           used  by an external program to determine if it was
                           invoked by Lynx.

                           See also the comments in the distribution's  sample
                           mailcap file, for notes on usage in such a file.

       TERM                Normally,   this   variable  is  used  by  Lynx  to
                           determine the terminal type being  used  to  invoke
                           Lynx.  If, however, it is unset at startup time (or
                           has the value "unknown"), or if the -term  command-
                           line  option  is  used (see OPTIONS section above),
                           Lynx will set or  modify  its  value  to  the  user
                           specified  terminal  type  (for  the Lynx execution
                           environment).  Note: If set/modified by  Lynx,  the
                           values  of  the  LINES  and/or  COLUMNS environment
                           variables may also be changed.

       If built with the cgi-links option enabled, Lynx allows access to a cgi
       script directly without the need for an http daemon.

       When  executing  such  "lynxcgi  scripts"  (if  enabled), the following
       variables may be set for simulating a CGI environment:














       Other environment variables are not inherited  by  the  script,  unless
       they   are   provided   via  a  LYNXCGI_ENVIRONMENT  statement  in  the
       configuration file.  See the lynx.cfg file, and  the  (draft)  CGI  1.1
       Specification <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The CGI Specification, and other associated  documentation,  should  be
       consulted for general information on CGI script programming.

       If  configured  and  installed  with Native Language Support, Lynx will
       display status and other messages in your local language.  See the file
       ABOUT_NLS  in  the  source distribution, or at your local GNU site, for
       more information about internationalization.

       The following environment  variables  may  be  used  to  alter  default

       LANG                This  variable,  if  set, will override the default
                           message language.  It is an ISO 639 two-letter code
                           identifying  the  language.  Language codes are NOT
                           the same as the country codes given in ISO 3166.

       LANGUAGE            This variable, if set, will  override  the  default
                           message language.  This is a GNU extension that has
                           higher priority for  setting  the  message  catalog
                           than LANG or LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These  variables,  if  set,  specify  the notion of
                           native language formatting style.  They are POSIXly

       LINGUAS             This  variable,  if  set  prior  to  configuration,
                           limits the installed languages to specific  values.
                           It  is  a space-separated list of two-letter codes.
                           Currently, it is hard-coded to a wish list.

       NLSPATH             This variable, if set, is used as the  path  prefix
                           for message catalogs.

       Note that man page availability and section numbering is somewhat plat-
       form dependent, and may vary from the above references.

       A section shown as (GNU), is intended to denote that the topic  may  be
       available via an info page, instead of a man page (i.e., try "info sub-
       ject", rather than "man subject").

       A section shown as (?) denotes that documentation on the topic  exists,
       but  is  not part of an established documentation retrieval system (see
       the distribution files associated with the topic, or contact your  Sys-
       tem Administrator for further information).

       Lynx  has  incorporated  code  from a variety of sources along the way.
       The earliest versions of Lynx included code from Earl Fogel of  Comput-
       ing  Services at the University of Saskatchewan, who implemented HYPER-
       REZ in the Unix environment.  HYPERREZ was developed by Niel Larson  of  and  served  as  the  model  for the early versions of Lynx.
       Those versions also incorporated libraries from the Unix Gopher clients
       developed  at  the  University  of Minnesota, and the later versions of
       Lynx rely on the WWW client library code developed by  Tim  Berners-Lee
       and  the  WWW  community.  Also a special thanks to Foteos Macrides who
       ported much of Lynx to VMS and did or organized most of its development
       since  the  departures of Lou Montulli and Garrett Blythe from the Uni-
       versity of Kansas in the summer of 1994 through the release of  v2.7.2,
       and  to  everyone  on the net who has contributed to Lynx's development
       either directly (through patches, comments or bug reports) or indirect-
       ly (through inspiration and development of other systems).
