- NAME
- rcsdiff - compare RCS revisions
-
- SYNOPSIS
- rcsdiff [ -biwt ] [ -cefhn ] [ -q ] [ -rrev1 ] [ -rrev2 ]
- file ...
-
- DESCRIPTION
- Rcsdiff runs diff(1) to compare two revisions of each RCS
- file given. A file name ending in ',v' is an RCS file name,
- otherwise a working file name. Rcsdiff derives the working
- file name from the RCS file name and vice versa, as
- explained in co(1L). Pairs consisting of both an RCS and a
- working file name may also be specified.
-
- The options -b, -i, -w, -t, -c, -e, -f, and -h, have the
- same effect as described in diff(1); option -n generates an
- edit script of the format used by RCS. The option -q
- suppresses diagnostic output.
-
- If both rev1 and rev2 are omitted, rcsdiff compares the
- latest revision on the default branch (normally the highest
- branch on 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,
- and may actually be attached to any of the options.
-
- EXAMPLES
- The command
-
- rcsdiff f.c
-
- runs diff on the latest revision on the default branch of
- RCS file f.c,v and the contents of working file f.c.
-
- DIAGNOSTICS
- The exit status is 0 if there were no differences during the
- last comparison, 1 if there were differences, and 2 if there
- were errors.
