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(1). 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.
