infocmp [-1CDEFGIKLTUVcdegilnpqrtux]
             [-v n] [-s d| i| l| c] [-R subset]
             [-w width] [-A directory] [-B directory]

       infocmp  can be used to compare a binary terminfo entry with other ter-
       minfo entries, rewrite a terminfo description to take advantage of  the
       use=  terminfo  field,  or  print  out  a terminfo description from the
       binary file (term) in a variety of formats.  In all cases, the  boolean
       fields  will be printed first, followed by the numeric fields, followed
       by the string fields.

   Default Options
       If no options are specified and zero or one  termnames  are  specified,
       the -I option will be assumed.  If more than one termname is specified,
       the -d option will be assumed.

   Comparison Options [-d] [-c] [-n]
       infocmp  compares  the  terminfo  description  of  the  first  terminal
       termname  with  each  of  the descriptions given by the entries for the
       other terminal's termnames.  If a capability is defined for only one of
       the  terminals, the value returned will depend on the type of the capa-
       bility: F for boolean variables, -1 for integer variables, and NULL for
       string variables.

       The  -d  option  produces  a  list of each capability that is different
       between two entries.  This option is  useful  to  show  the  difference
       between two entries, created by different people, for the same or simi-
       lar terminals.

       The -c option produces a list of each capability that is common between
       two  or more entries.  Capabilities that are not set are ignored.  This
       option can be used as a quick check to see if the -u  option  is  worth

       The -n option produces a list of each capability that is in none of the
       given entries.  If no termnames are  given,  the  environment  variable
       TERM  will  be  used  for both of the termnames.  This can be used as a
       quick check to see if anything was left out of a description.

   Source Listing Options [-I] [-L] [-C] [-r]
       The -I, -L, and -C options will produce a source listing for each  ter-
       minal named.

            -I   use the terminfo names
            -L   use the long C variable name listed in <term.h>
            -C   use the termcap names
            -r   when using -C, put out all capabilities in termcap form
            -K   modifies the -C option, improving BSD-compatibility.

       If  no  termnames are given, the environment variable TERM will be used
       unlimited size of termcap, you may want to add  the  -T  option.   More
       often  however,  you  must  help  the  termcap implementation, and trim
       excess whitespace (use the -0 option for that).

       All padding information for strings  will  be  collected  together  and
       placed at the beginning of the string where termcap expects it.  Manda-
       tory padding (padding information with  a  trailing  '/')  will  become

       All  termcap  variables  no longer supported by terminfo, but which are
       derivable from other terminfo variables, will be output.  Not all  ter-
       minfo  capabilities will be translated; only those variables which were
       part of termcap will normally be output.  Specifying the -r option will
       take  off  this  restriction, allowing all capabilities to be output in
       termcap form.  Normally you would use both the -C and -r options.   The
       actual  format  used incorporates some improvements for escaped charac-
       ters from terminfo format.  For a stricter BSD-compatible  translation,
       use the -K option rather than -C.

       Note that because padding is collected to the beginning of the capabil-
       ity, not all capabilities are output.  Mandatory padding  is  not  sup-
       ported.   Because termcap strings are not as flexible, it is not always
       possible to convert a terminfo string  capability  into  an  equivalent
       termcap  format.  A subsequent conversion of the termcap file back into
       terminfo format will not necessarily reproduce  the  original  terminfo

       Some  common  terminfo  parameter sequences, their termcap equivalents,
       and some terminal types which commonly have such sequences, are:

           terminfo                    termcap   Representative Terminals
           %p1%c                       %.        adm
           %p1%d                       %d        hp, ANSI standard, vt100
           %p1%'x'%+%c                 %+x       concept
           %i                          %iq       ANSI standard, vt100
           %p1%?%'x'%>%t%p1%'y'%+%;    %>xy      concept
           %p2 is printed before %p1   %r        hp

   Use= Option [-u]
       The -u option produces a terminfo source description of the first  ter-
       minal  termname  which is relative to the sum of the descriptions given
       by the entries for the other terminals termnames.  It does this by ana-
       lyzing  the  differences  between  the  first  termname  and  the other
       termnames and producing a description with use= fields  for  the  other
       terminals.  In this manner, it is possible to retrofit generic terminfo
       entries into a terminal's description.  Or, if  two  similar  terminals
       exist, but were coded at different times or by different people so that
       each description is a full description, using infocmp  will  show  what
       can be done to change one description to be relative to the other.

       A  capability  will  get  printed  with  an at-sign (@) if it no longer
       exists in the first termname, but one of  the  other  termname  entries
       contains  a  value  for  it.   A capability's value gets printed if the
       Alternatively, specifying a capability after a use= entry that contains
       that  capability  will  cause  the  second specification to be ignored.
       Using infocmp to recreate a description can be a useful check  to  make
       sure  that  everything  was  specified correctly in the original source

       Another error that does not cause incorrect compiled  files,  but  will
       slow  down  the  compilation time, is specifying extra use= fields that
       are superfluous.  infocmp will flag any other termname use= fields that
       were not needed.

   Changing Databases [-A directory] [-B directory]
       Like  other  ncurses utilities, infocmp looks for the terminal descrip-
       tions in several places.  You can use the  TERMINFO  and  TERMINFO_DIRS
       environment  variables  to  override  the  compiled-in  default list of
       places to search (see curses(3X) for details).

       You can also use the options -A and -B to override the list  of  places
       to search when comparing terminal descriptions:

       o   The -A option sets the location for the first termname

       o   The -B option sets the location for the other termnames.

       Using  these options, it is possible to compare descriptions for a ter-
       minal with the same name  located  in  two  different  databases.   For
       instance,  you  can use this feature for comparing descriptions for the
       same terminal created by different people.

   Other Options
       -0   causes the fields to be printed on one line, without wrapping.

       -1   causes the fields to be printed out one to a line.  Otherwise, the
            fields  will be printed several to a line to a maximum width of 60

       -a   tells infocmp to retain  commented-out  capabilities  rather  than
            discarding  them.   Capabilities  are  commented by prefixing them
            with a period.

       -D   tells infocmp to print the database locations that it knows about,
            and exit.

       -E   Dump  the  capabilities of the given terminal as tables, needed in
            the C initializer for a TERMTYPE structure (the terminal  capabil-
            ity structure in the <term.h>).  This option is useful for prepar-
            ing versions of the curses library hardwired for a given  terminal
            type.  The tables are all declared static, and are named according
            to the type and the name of the corresponding terminal entry.

            Before ncurses 5.0, the split between the -e and  -E  options  was
            not  needed;  but  support  for extended names required making the
            arrays of terminal capabilities separate from the TERMTYPE  struc-
            difference report.  Normally, to reduce the volume of the  report,
            use  references  are  not resolved before looking for differences,
            but resolution can be forced by also specifying -r.

       -f   Display complex terminfo strings which contain  if/then/else/endif
            expressions indented for readability.

       -G   Display  constant literals in decimal form rather than their char-
            acter equivalents.

       -g   Display constant character literals in  quoted  form  rather  than
            their decimal equivalents.

       -i   Analyze  the  initialization (is1, is2, is3), and reset (rs1, rs2,
            rs3), strings in the entry.  For each string, the  code  tries  to
            analyze  it into actions in terms of the other capabilities in the
            entry, certain X3.64/ISO 6429/ECMA-48  capabilities,  and  certain
            DEC  VT-series  private  modes  (the  set  of  recognized  special
            sequences has been selected for  completeness  over  the  existing
            terminfo  database).   Each report line consists of the capability
            name, followed by a colon  and  space,  followed  by  a  printable
            expansion  of  the capability string with sections matching recog-
            nized actions translated into {}-bracketed descriptions.  Here  is
            a list of the DEC/ANSI special sequences recognized: i.

            archaic versions of terminfo like those on SVr1, Ultrix, or  HP/UX
            that  do not support the full set of SVR4/XSI Curses terminfo; and
            variants such as AIX that have their own  extensions  incompatible
            with  SVr4/XSI.   Available terminfo subsets are "SVr1", "Ultrix",
            "HP", and "AIX"; see terminfo(5) for details.  You can also choose
            the  subset  "BSD"  which  selects  only capabilities with termcap
            equivalents recognized by 4.4BSD.

       -s [d|i|l|c]
            The -s option sorts the fields within each type according  to  the
            argument below:

            d    leave  fields  in  the order that they are stored in the ter-
                 minfo database.

            i    sort by terminfo name.

            l    sort by the long C variable name.

            c    sort by the termcap name.

            If the -s option is not given, the  fields  printed  out  will  be
            sorted  alphabetically  by  the  terminfo  name  within each type,
            except in the case of the -C or the -L options,  which  cause  the
            sorting  to  be  done  by  the termcap name or the long C variable
            name, respectively.

       -T   eliminates size-restrictions  on  the  generated  text.   This  is
            mainly  useful  for  testing  and  analysis,  since  the  compiled
            descriptions are limited (e.g., 1023 for termcap,  4096  for  ter-

       -t   tells  tic  to  discard commented-out capabilities.  Normally when
            translating from terminfo to termcap, untranslatable  capabilities
            are commented-out.

       -U   tells  infocmp  to  not  post-process  the  data after parsing the
            source file.  This feature helps when comparing  the  actual  con-
            tents  of  two source files, since it excludes the inferences that
            infocmp makes to fill in missing data.
