NAME

      rlog - print log messages and other information about RCS files


SYNOPSIS

      rlog [ options ] file ...


DESCRIPTION

      rlog prints information about RCS files.

      Pathnames 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 pathname,
      working pathname, 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
          translating a working pathname into an RCS pathname.

      -h  Print only the RCS pathname, working pathname, 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.

      -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
          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.

      -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.

      -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

DIAGNOSTICS

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

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.
