NAME
rlog - print log messages and other information about RCS files

SYNOPSIS
rlog [ options ] file ...

DESCRIPTION
Rlog prints information about RCS files. Files ending in ‘,v’ are
RCS files, all others are working files. If a working file is
given, rlog tries to find the corresponding RCS file first in
directory ./RCS and then in the current directory, as explained in
co(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. Without options, rlog
prints complete information. The options below restrict this
output.

-L ignores RCS files that have no locks set; convenient in
combination with -R, -h, or -l.

-R only prints the name of the RCS file; convenient for
translating a working file name into an RCS file name.

-h prints only RCS file name, working file name, head,
default branch, access list, locks, symbolic names, and
suffix.

-t prints the same as -h, plus the descriptive text.

-b prints information about the revisions on the default
branch (normally the highest branch on the trunk).

-ddates prints 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, (inclusive). A range of the form <d or d> selects
all revisions dated d or earlier. A range of the form d<
or >d selects all revisions dated d or later. 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]
prints information about locked revisions. If the
comma-separated list lockers of login names is given,
only the revisions locked by the given login names are
printed. If the list is omitted, all locked revisions
are printed.

-rrevisions
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.

-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.

Rlog prints the intersection of the revisions selected with the
options -d, -l, -s, -w, intersected with the union of the revisions
selected by -b and -r.

EXAMPLES
rlog -L -R RCS/*,v
rlog -L -h RCS/*,v
rlog -L -l RCS/*,v
rlog RCS/*,v

The first command prints the names of all RCS files in the
subdirectory ‘RCS’ which 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.

DIAGNOSTICS
The exit status always refers to the last RCS file operated upon,
and is 0 if the operation was successful, 1 otherwise.
