       rlog - print log messages and other information about RCS files


       rlog [ options ] file ...


       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

       -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  translating  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,  normally  the  highest
           branch on the trunk.

           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.

           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.

           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 containing 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.

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

           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.

           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


           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


              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.  Useful RCSINIT options include -q, -V, -x, and -z.

              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 kilobytes).  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.


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

       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.
