- NAME
- rcsdiff - compare RCS revisions
-
- SYNOPSIS
- rcsdiff [ -ksubst ] [ -q ] [ -rrev1 [ -rrev2 ] ] [ -Vn ] [
- -xsuffixes ] [ diff options ] file ...
-
- 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 -V and -x. 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.
