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 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.
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
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.
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
-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/*
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.
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.
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.
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
should give you access to the complete manual. Additionally, the RCS
has news and links to the latest release, development site, etc.
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.
