RLOG(1) General Commands Manual RLOG(1)
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

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.
