|
.SH DESCRIPTION
|
|
.B rcsdiff
|
|
runs
|
|
.BR diff (1)
|
|
to compare two revisions of each \*r file given.
|
|
.PP
|
|
Pathnames matching an \*r suffix denote \*r files;
|
|
all others denote working files.
|
|
Names are paired as explained in
|
|
.BR ci (1).
|
|
.PP
|
|
The option
|
|
.B \-q
|
|
suppresses diagnostic output.
|
|
Zero, one, or two revisions may be specified with
|
|
.BR \-r .
|
|
The option
|
|
.BI \-k subst
|
|
affects keyword substitution when extracting
|
|
revisions, as described in
|
|
.BR co (1);
|
|
for example,
|
|
.B "\-kk\ \-r1.1\ \-r1.2"
|
|
ignores differences in keyword values when comparing revisions
|
|
.B 1.1
|
|
and
|
|
.BR 1.2 .
|
|
To avoid excess output from locker name substitution,
|
|
.B \-kkvl
|
|
is assumed if (1) at most one revision option is given,
|
|
(2) no
|
|
.B \-k
|
|
option is given, (3)
|
|
.B \-kkv
|
|
is the default keyword substitution, and
|
|
(4) the working file's mode would be produced by
|
|
.BR "co\ \-l".
|
|
See
|
|
.BR co (1)
|
|
for details
|
|
about
|
|
.B \-V
|
|
and
|
|
.BR \-x .
|
|
Otherwise, all options of
|
|
.BR diff (1)
|
|
that apply to regular files are accepted, with the same meaning as for
|
|
.BR diff .
|
|
.PP
|
|
If both
|
|
.I rev1
|
|
and
|
|
.I rev2
|
|
are omitted,
|
|
.B 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.
|
|
.PP
|
|
If
|
|
.I rev1
|
|
is given, but
|
|
.I rev2
|
|
is omitted,
|
|
.B rcsdiff
|
|
compares revision
|
|
.I rev1
|
|
of the \*r file with
|
|
the contents of the corresponding working file.
|
|
.PP
|
|
If both
|
|
.I rev1
|
|
and
|
|
.I rev2
|
|
are given,
|
|
.B rcsdiff
|
|
compares revisions
|
|
.I rev1
|
|
and
|
|
.I rev2
|
|
of the \*r file.
|
|
.PP
|
|
Both
|
|
.I rev1
|
|
and
|
|
.I rev2
|
|
may be given numerically or symbolically.
|
|
.SH EXAMPLE
|

|

|
|
.LP
|

compares the latest revision on the default branch of the \*r file
|
|
to the contents of the working file
|
|
.BR f.c .
|
|
.SH ENVIRONMENT
|
|
.TP
|
