RCSDIFF(1)RCSDIFF(1)NAMErcsdiff - compare RCS revisions
SYNOPSISrcsdiff [ -ksubst ] [ -q ] [ -rrev1 [ -rrev2 ] ] [ -T ] [
-V[n] ] [ -xsuffixes ] [ -zzone ] [ diff options ] file
...
DESCRIPTIONrcsdiff 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 revi-
sions, as described in co(1); for example, -kk -r1.1 -r1.2
ignores differences in keyword values when comparing revi-
sions 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 RCS file with the contents of the
corresponding working file.
If both rev1 and rev2 are given, rcsdiff compares revi-
sions rev1 and rev2 of the RCS file.
Both rev1 and rev2 may be given numerically or symboli-
cally.
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.

DIAGNOSTICS
Exit status is 0 for no differences during any comparison,
1 for some differences, 2 for trouble.
