The
rcsdiff program is used to compare
revisions of RCS files, in much the same way as the
diff(1) utility. Differences
between two specific revisions can be requested, as well as differences
between the current working file and the latest revision of the default
branch.
It is not possible to display differences between entire directories, or
differences between more than two files. All diffs produced are in the
standard diff format, unless the
-u option
is specified, which produces unified diffs.
rcsdiff also supports keyword substitution
– see the
rcs(1) man page
for more information.
The following options are supported:
-
-
-c- Produces a diff with three lines of context. See
diff(1) for more
information.
-
-
-kmode- Specify the keyword substitution mode.
-
-
-n- Produces a diff in the same format that is used in the RCS files.
-
-
-q- Be quiet about reporting.
-
-
-rrev- Produces a diff with respect to revision
rev. This option should be specified
twice to generate a diff between two specific revisions. If only one
revision is specified, diffing is done between that revision and the
current working file.
-
-
-u- Produces a unified diff with three lines of context. See
diff(1) for more
information.
-
-
-V- Print RCS's version number.
-
-
-xsuffixes- Specifies the suffixes for RCS files. Suffixes should be separated by the
‘/’ character.
-
-
-ztz- Specify the date output format.
-
-
- diff_options
- Most of the options documented in
diff(1) may also be
specified.
-
-
RCSINIT- If set, this variable should contain a list of space-delimited options
that are prepended to the argument list.
-
-
TMPDIR- When set, this variable specifies the directory where temporary files are
to be created. The default is set to
/tmp.
The
rcsdiff utility exits with one of the
following values:
- 0
- No differences were found.
- 1
- Differences were found.
- 2
- An error occurred.
Compare the latest revision of the default branch with the content of working
file
foo.c:
$ rcsdiff foo.c
Compare revision 1.7 and 1.8 of file
foo.c
and ignore differences in keyword values:
$ rcsdiff -kk -r1.7 -r1.8
foo.c
