NAME
rcsdiff - compare RCS revisions
SYNOPSIS
rcsdiff [ -ksubst ] [ -q ] [ -rrev1 [ -rrev2 ] ] [ -Vn ] [
-xsuffixes ] [ diff options ] file ...
DESCRIPTION
rcsdiff runs diff(1) to compare two revisions of each RCS
file given.
Pathnames matching an RCS suffix denote RCS 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 -ksubst
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 -V and -x. 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 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.
EXAMPLE
The command
rcsdiff f.c
compares the latest revision on the default branch of the
RCS file to the contents of the working file f.c.
ENVIRONMENT
RCSINIT
options prepended to the argument list, separated by
spaces. See ci(1) for details.
DIAGNOSTICS
Exit status is 0 for no differences during any comparison, 1
for some differences, 2 for trouble.
