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
Filenames matching an
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 -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

Options prepended to the argument list, separated by spaces.
A backslash escapes spaces within an option.
RCSINIToptions are prepended to the argument lists of mostRCScommands. UsefulRCSINIToptions include -q, -V, -x, and -z.
Normally, for speed, commands either memory map or copy into memory
the RCSfile if its size is less than the memory-limit, currently defaulting to ``unlimited''. Otherwise (or if the initially-tried speedy ways fail), the commands fall back to using standard i/o routines. You can adjust the memory limit by settingRCS_MEM_LIMITto a numeric value lim (measured in kilobytes). An empty value is silently ignored. As a side effect, specifyingRCS_MEM_LIMITinhibits fall-back to slower routines.
Name of the temporary directory.
If not set, the environment variables
TMPandTEMPare inspected instead and the first value found is taken; if none of them are set, a host-dependent default is used, typically /tmp.
DIAGNOSTICSExit status is 0 for no differences during any comparison, 1 for some differences, 2 for trouble.
