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 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
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
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.
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.
