rcsdiff \- compare RCS revisions

.SH SYNOPSIS
|
|
\fBrcsdiff\fR [ \fB\-biwt\fR ] [ \fB\-cefhn\fR ] [ \fB\-q\fR ] [ \fB\-r\fIrev1\fR ] [ \fB\-r\fIrev2\fR ] file ...
|
|
.SH DESCRIPTION
|
|
.I Rcsdiff
|
|
runs
|
|
.IR 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. \fIRcsdiff\fR derives the working file name from the RCS
|
|
file name and vice versa, as explained in
|
|
.IR co (1L).
|
|
Pairs consisting
|
|
of both an RCS and a working file name may also be specified.
|
|
.PP
|
|
The options \fB\-b\fR, \fB\-i\fR, \fB\-w\fR, \fB\-t\fR,
|
|
\fB\-c\fR, \fB\-e\fR, \fB\-f\fR, and \fB\-h\fR,
|
|
have the same effect as described in
|
|
.IR diff (1);
|
|
option
|
|
\fB\-n\fR generates an edit script of the format used by RCS.
|
|
The option \fB\-q\fR suppresses diagnostic output.
|
|
.PP
|
|
If both \fIrev1\fR and \fIrev2\fR
|
|
are omitted, \fIrcsdiff\fR 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.
|
|
.PP
|
|
If \fIrev1\fR is given, but \fIrev2\fR is omitted,
|
|
\fIrcsdiff\fR compares revision \fIrev1\fR of the RCS file with
|
|
the contents of the corresponding working file.
|
|
.PP
|
|
If both \fIrev1\fR and \fIrev2\fR are given,
|
|
\fIrcsdiff\fR compares revisions \fIrev1\fR and \fIrev2\fR of the RCS file.
|
|
.PP
|
|
Both \fIrev1\fR and \fIrev2\fR may be given numerically or symbolically,
|
|
and may actually be attached to any of the options.
|
|
.SH EXAMPLES
|
|
.nf
|
|
The command
|
|
|
|
.B " rcsdiff f.c
|
|
|
|
.fi
|
|
runs \fIdiff\fR on the latest revision on the default branch of RCS file f.c,v
|
|
and the contents of working file f.c.
|
|
.SH 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.
