rcsdiff runs
diff(1) to compare two revisions of each r file given.
Pathnames matching an r suffix denote r 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
-k subst 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 r file with
the contents of the corresponding working file.
If both
rev1 and
rev2 are given,
rcsdiff compares revisions
rev1 and
rev2 of the r 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 r file
to the contents of the working file
f.c .

DIAGNOSTICS
Exit status is 0 for no differences during any comparison,
1 for some differences, 2 for trouble.
