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 num-
       ber, 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
	   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.

       -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  inclu-
	   sive,  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 separa-
	   tor 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.

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

       RCS_MEM_LIMIT
	      An integer lim, measured in kilobytes, specifying the threshold  under  which  com-
	      mands  will  try	to use memory-based operations for processing the RCS file.  (For
	      RCS files of size lim kilobytes or  greater,  RCS  will  use  the  slower  standard
	      input/output routines.)  Default value is 256.

       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.
