RLOG(1)                     General Commands Manual                    RLOG(1)

NAME
       rlog - print log messages and other information about RCS files

SYNOPSIS
       rlog [ options ] file ...

DESCRIPTION
       rlog prints information about RCS files.

       Filenames  matching  an  RCS suffix denote RCS files; all others denote
       working files.  Names are paired as explained in ci(1).

       rlog prints the following information for each RCS file: RCS file name,
       working file name, head (i.e., the number of the latest revision on the
       trunk), default branch, access list,  locks,  symbolic  names,  suffix,
       total  number  of revisions, number of revisions selected for printing,
       and descriptive text.  This is followed by  entries  for  the  selected
       revisions  in  reverse  chronological  order for each branch.  For each
       revision, rlog prints revision number, author, date/time, state, number
       of  lines added/deleted (with respect to the previous revision), locker
       of the revision (if any), and log message.  All times are displayed  in
       Coordinated  Universal  Time  (UTC)  by default; this can be overridden
       with -z.  Without  options,  rlog  prints  complete  information.   The
       options below restrict this output.

       -L  Ignore  RCS  files  that  have no locks set.  This is convenient in
           combination with -h, -l, and -R.

       -R  Print only the name of the RCS file.  This is convenient for trans-
           lating a working file name into an RCS file name.

       -h  Print  only  the  RCS  file  name, working file name, head, default
           branch, access list, locks, symbolic names, and suffix.

       -t  Print the same as -h, plus the descriptive text.

       -N  Do not print the symbolic names.

       -b  Print information about the revisions on the default  branch,  nor-
           mally the highest branch on the trunk.

       -ddates
           Print  information  about revisions with a checkin date/time in the
           ranges given by the semicolon-separated list of dates.  A range  of
           the  form  d1<d2 or d2>d1 selects the revisions that were deposited
           between d1 and d2 exclusive.  A range of the form <d or d>  selects
           all revisions earlier than d.  A range of the form d< or >d selects
           all revisions dated later than d.  If < or > is followed by =  then
           the  ranges  are  inclusive,  not exclusive.  A range of the form d
           selects the single,  latest  revision  dated  d  or  earlier.   The
           date/time strings d, d1, and d2 are in the free format explained in
           co(1).  Quoting is normally necessary,  especially  for  <  and  >.
           Note that the separator is a semicolon.

       -l[lockers]
           Print information about locked revisions only.  In addition, if the
           comma-separated list lockers of login names is  given,  ignore  all
           locks   other  than  those  held  by  the  lockers.   For  example,
           rlog -L -R -lwft RCS/* prints the name of RCS files locked  by  the
           user wft.

       -r[revisions]
           prints  information  about  revisions  given in the comma-separated
           list revisions of revisions and ranges.  A  range  rev1:rev2  means
           revisions  rev1  to  rev2  on the same branch, :rev means revisions
           from the beginning of the branch up to and including rev, and  rev:
           means revisions starting with rev to the end of the branch contain-
           ing rev.  An argument that is a branch means all revisions on  that
           branch.  A range of branches means all revisions on the branches in
           that range.  A branch followed by a . means the latest revision  in
           that branch.  A bare -r with no revisions means the latest revision
           on the default branch, normally the trunk.

       -sstates
           prints information about revisions whose state attributes match one
           of the states given in the comma-separated list states.

       -w[logins]
           prints  information  about revisions checked in by users with login
           names appearing in the comma-separated list logins.  If  logins  is
           omitted, the user's login is assumed.

       -q  This  option  has  no  effect;  it is provided for consistency with
           other commands.

       -T  This option has no effect; it is  present  for  compatibility  with
           other RCS commands.

       -V  Print RCS's version number.

       -Vn Emulate RCS version n when generating logs.  See co(1) for more.

       -xsuffixes
           Use suffixes to characterize RCS files.  See ci(1) for details.

       rlog prints the intersection of the revisions selected with the options
       -d, -l, -s, and  -w,  intersected  with  the  union  of  the  revisions
       selected by -b and -r.

       -zzone specifies the date output format, and specifies the default time
              zone for date in the -ddates option.  The zone should be  empty,
              a  numeric  UTC offset, or the special string LT for local time.
              The default is an empty zone, which  uses  the  traditional  RCS
              format  of UTC without any time zone indication and with slashes
              separating the parts of the date; otherwise, times are output in
              ISO  8601  format  with  time  zone indication.  For example, if
              local time is January 11, 1990, 8pm Pacific Standard Time, eight
              hours west of UTC, then the time is output as follows:

                     option    time output
                     -z        1990/01/12 04:00:00        (default)
                     -zLT      1990-01-11 20:00:00-08
                     -z+05:30  1990-01-12 09:30:00+05:30

EXAMPLES
           rlog  -L  -R  RCS/*
           rlog  -L  -h  RCS/*
           rlog  -L  -l  RCS/*
           rlog  RCS/*

       The first command prints the names of all RCS files in the subdirectory
       RCS that have locks.  The second command prints the  headers  of  those
       files,  and  the  third prints the headers plus the log messages of the
       locked revisions.  The last command prints complete information.

ENVIRONMENT
       RCSINIT
              Options prepended to the argument list, separated by spaces.   A
              backslash  escapes spaces within an option.  The RCSINIT options
              are prepended to the argument lists of most RCS commands.   Use-
              ful RCSINIT options include -q, -V, -x, and -z.

       RCS_MEM_LIMIT
              Normally,  for  speed,  commands  either memory map or copy into
              memory the RCS file if its size is less than  the  memory-limit,
              currently  defaulting  to  ``unlimited''.   Otherwise (or if the
              initially-tried speedy ways fail), the  commands  fall  back  to
              using standard i/o routines.  You can adjust the memory limit by
              setting RCS_MEM_LIMIT to a numeric value lim (measured in  kilo-
              bytes).   An empty value is silently ignored.  As a side effect,
              specifying RCS_MEM_LIMIT inhibits fall-back to slower routines.

       TMPDIR Name of the temporary directory.  If not  set,  the  environment
              variables TMP and TEMP are inspected instead and the first value
              found is taken; if  none  of  them  are  set,  a  host-dependent
              default is used, typically /tmp.

DIAGNOSTICS
       The exit status is zero if and only if all operations were successful.

       The full documentation for RCS is maintained as a Texinfo  manual.   If
       the  info(1)  and RCS programs are properly installed at your site, the
       command

              info rcs

       should give you access to the complete manual.  Additionally,  the  RCS
       homepage:

       has news and links to the latest release, development site, etc.

BUGS
       The separator for revision ranges in the -r option used to be - instead
       of :, but this leads to confusion when symbolic names contain  -.   For
       backwards compatibility rlog -r still supports the old - separator, but
       it warns about this obsolete use.
