12 rlog prints information about RCS files.
13 Filenames matching an RCS suffix denote RCS files; all others denote
15 working files. Names are paired as explained in ci(1).
16 rlog prints the following information for each RCS file: RCS file name,
18 working file name, head (i.e., the number of the latest revision on the
19 trunk), default branch, access list, locks, symbolic names, suffix, to‐
20 tal number of revisions, number of revisions selected for printing, and
21 descriptive text. This is followed by entries for the selected revi‐
22 sions in reverse chronological order for each branch. For each revi‐
23 sion, rlog prints revision number, author, date/time, state, number of
24 lines added/deleted (with respect to the previous revision), locker of
25 the revision (if any), and log message. All times are displayed in Co‐
26 ordinated Universal Time (UTC) by default; this can be overridden with
27 -z. Without options, rlog prints complete information. The options
28 below restrict this output.
29 -L Ignore RCS files that have no locks set. This is convenient in
31 combination with -h, -l, and -R.
32 -R Print only the name of the RCS file. This is convenient for trans‐
34 lating a working file name into an RCS file name.
35 -h Print only the RCS file name, working file name, head, default
37 branch, access list, locks, symbolic names, and suffix.
38 -t Print the same as -h, plus the descriptive text.
40 -N Do not print the symbolic names.
42 -b Print information about the revisions on the default branch, nor‐
44 mally the highest branch on the trunk.
45 -ddates
47 Print information about revisions with a checkin date/time in the
48 ranges given by the semicolon-separated list of dates. A range of
49 the form d1<d2 or d2>d1 selects the revisions that were deposited
50 between d1 and d2 exclusive. A range of the form <d or d> selects
51 all revisions earlier than d. A range of the form d< or >d selects
52 all revisions dated later than d. If < or > is followed by = then
53 the ranges are inclusive, not exclusive. A range of the form d se‐
54 lects the single, latest revision dated d or earlier. The
55 date/time strings d, d1, and d2 are in the free format explained in
56 co(1). Quoting is normally necessary, especially for < and >.
57 Note that the separator is a semicolon.
58 -l[lockers]
60 Print information about locked revisions only. In addition, if the
61 comma-separated list lockers of login names is given, ignore all
62 locks other than those held by the lockers. For example,
63 rlog -L -R -lwft RCS/* prints the name of RCS files locked by the
64 user wft.
65 -r[revisions]
67 prints information about revisions given in the comma-separated
68 list revisions of revisions and ranges. A range rev1:rev2 means
69 revisions rev1 to rev2 on the same branch, :rev means revisions
70 from the beginning of the branch up to and including rev, and rev:
71 means revisions starting with rev to the end of the branch contain‐
72 ing rev. An argument that is a branch means all revisions on that
73 branch. A range of branches means all revisions on the branches in
74 that range. A branch followed by a . means the latest revision in
75 that branch. A bare -r with no revisions means the latest revision
76 on the default branch, normally the trunk.
77 -sstates
79 prints information about revisions whose state attributes match one
80 of the states given in the comma-separated list states.
81 -w[logins]
83 prints information about revisions checked in by users with login
84 names appearing in the comma-separated list logins. If logins is
85 omitted, the user's login is assumed.
86 -q This option has no effect; it is provided for consistency with
88 other commands.
89 -T This option has no effect; it is present for compatibility with
91 other RCS commands.
92 -V Print RCS's version number.
94 -Vn Emulate RCS version n when generating logs. See co(1) for more.
96 -xsuffixes
98 Use suffixes to characterize RCS files. See ci(1) for details.
99 rlog prints the intersection of the revisions selected with the options
101 -d, -l, -s, and -w, intersected with the union of the revisions se‐
102 lected by -b and -r.
103 -zzone specifies the date output format, and specifies the default time
105 zone for date in the -ddates option. The zone should be empty,
106 a numeric UTC offset, or the special string LT for local time.
107 The default is an empty zone, which uses the traditional RCS
108 format of UTC without any time zone indication and with slashes
109 separating the parts of the date; otherwise, times are output in
110 ISO 8601 format with time zone indication. For example, if lo‐
111 cal time is January 11, 1990, 8pm Pacific Standard Time, eight
112 hours west of UTC, then the time is output as follows:
113 option time output
115 -z 1990/01/12 04:00:00 (default)
116 -zLT 1990-01-11 20:00:00-08
117 -z+05:30 1990-01-12 09:30:00+05:30

120 rlog -L -R RCS/*
121 rlog -L -h RCS/*
122 rlog -L -l RCS/*
123 rlog RCS/*
124 The first command prints the names of all RCS files in the subdirectory
126 RCS that have locks. The second command prints the headers of those
127 files, and the third prints the headers plus the log messages of the
128 locked revisions. The last command prints complete information.
129
131 RCSINIT
132 Options prepended to the argument list, separated by spaces. A
133 backslash escapes spaces within an option. The RCSINIT options
134 are prepended to the argument lists of most RCS commands. Use‐
135 ful RCSINIT options include -q, -V, -x, and -z.
136 RCS_MEM_LIMIT
138 Normally, for speed, commands either memory map or copy into
139 memory the RCS file if its size is less than the memory-limit,
140 currently defaulting to ``unlimited''. Otherwise (or if the
141 initially-tried speedy ways fail), the commands fall back to us‐
142 ing standard i/o routines. You can adjust the memory limit by
143 setting RCS_MEM_LIMIT to a numeric value lim (measured in kilo‐
144 bytes). An empty value is silently ignored. As a side effect,
145 specifying RCS_MEM_LIMIT inhibits fall-back to slower routines.
146 TMPDIR Name of the temporary directory. If not set, the environment
148 variables TMP and TEMP are inspected instead and the first value
149 found is taken; if none of them are set, a host-dependent de‐
150 fault is used, typically /tmp.
151
153 The exit status is zero if and only if all operations were successful.

182 The separator for revision ranges in the -r option used to be - instead
183 of :, but this leads to confusion when symbolic names contain -. For
184 backwards compatibility rlog -r still supports the old - separator, but
185 it warns about this obsolete use.
