DESCRIPTION
rcsdiff runs
diff(1) to compare two revisions of each RCS file
given.
Pathnames matching an RCS suffix denote RCS files; all others denote working
files. Names are paired as explained in
ci(1).
The option
-q suppresses diagnostic output. Zero, one, or two revisions
may be specified with
-r. The option
-ksubst affects
keyword substitution when extracting revisions, as described in
co(1);
for example,
-kk -r1.1 -r1.2 ignores differences in keyword
values when comparing revisions
1.1 and
1.2. To avoid excess
output from locker name substitution,
-kkvl is assumed if (1) at most
one revision option is given, (2) no
-k option is given, (3)
-kkv is the default keyword substitution, and (4) the working file's
mode would be produced by
co -l. See
co(1) for details
about
-T,
-V,
-x and
-z. Otherwise, all options of
diff(1) that apply to regular files are accepted, with the same meaning
as for
diff.
If both
rev1 and
rev2 are omitted,
rcsdiff compares the
latest revision on the default branch (by default the trunk) with the contents
of the corresponding working file. This is useful for determining what you
changed since the last checkin.
If
rev1 is given, but
rev2 is omitted,
rcsdiff compares
revision
rev1 of the RCS file with the contents of the corresponding
working file.
If both
rev1 and
rev2 are given,
rcsdiff compares revisions
rev1 and
rev2 of the RCS file.
Both
rev1 and
rev2 may be given numerically or symbolically.
EXAMPLE
The command
rcsdiff f.c
compares the latest revision on the default branch of the RCS file to the
contents of the working file
f.c.
ENVIRONMENT
- RCSINIT
- options prepended to the argument list, separated by
spaces. See ci(1) for details.
DIAGNOSTICS
Exit status is 0 for no differences during any comparison, 1 for some
differences, 2 for trouble.
