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 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.
