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
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
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.
- -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
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.
- 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
- 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 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:
- http://www.gnu.org/software/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.
