rcsdiff
runs
diff (1)
to compare two revisions of each \*r file given.
Pathnames matching an \*r suffix denote \*r files;
all others denote working files.
Names are paired as explained in
ci (1).
The option
-q
suppresses diagnostic output.
Zero, one, or two revisions may be specified with
-r .
The option
-k subst
affects keyword substitution when extracting
revisions, as described in
co (1);
for example,
-kk\ -r1.1\ -r1.2
ignores differences in keyword values when comparing revisions
1.1
and
1.2 .
To avoid excess output from locker name substitution,
-kkvl
is assumed if (1) at most one revision option is given,
(2) no
-k
option is given, (3)
-kkv
is the default keyword substitution, and
(4) the working file's mode would be produced by
co\ -l .
See
co (1)
for details
about
-T ,
-V ,
-x
and
-z .
Otherwise, all options of
diff (1)
that apply to regular files are accepted, with the same meaning as for
diff .
If both
rev1
and
rev2
are omitted,
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.
If
rev1
is given, but
rev2
is omitted,
rcsdiff
compares revision
rev1
of the \*r file with
the contents of the corresponding working file.
If both
rev1
and
rev2
are given,
rcsdiff
compares revisions
rev1
and
rev2
of the \*r file.
Both
rev1
and
rev2
may be given numerically or symbolically.
