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 trans-
   lating 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, 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.

    -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.
    See ci(1) for details.

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.
