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 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 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 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
-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 com‐
mand 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 commands 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.

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.
