NAME
rcsclean - clean up working files
SYNOPSIS
rcsclean [
options] [
file ... ]
DESCRIPTION
rcsclean removes files that are not being worked on.
rcsclean -u
also unlocks and removes files that are being worked on but have not changed.
For each
file given,
rcsclean compares the working file and a
revision in the corresponding RCS file. If it finds a difference, it does
nothing. Otherwise, it first unlocks the revision if the
-u option is
given, and then removes the working file unless the working file is writable
and the revision is locked. It logs its actions by outputting the
corresponding
rcs -u and
rm -f commands on the standard output.
Files are paired as explained in
ci(1). If no
file is given, all
working files in the current directory are cleaned. Pathnames matching an RCS
suffix denote RCS files; all others denote working files.
The number of the revision to which the working file is compared may be attached
to any of the options
-n,
-q,
-r, or
-u. If no
revision number is specified, then if the
-u option is given and the
caller has one revision locked,
rcsclean uses that revision; otherwise
rcsclean uses the latest revision on the default branch, normally the
root.
rcsclean is useful for
clean targets in makefiles. See also
rcsdiff(1), which prints out the differences, and
ci(1), which
normally reverts to the previous revision if a file was not changed.
OPTIONS
- -ksubst
- Use subst style keyword substitution when retrieving
the revision for comparison. See co(1) for details.
- -n[rev]
- Do not actually remove any files or unlock any revisions.
Using this option will tell you what rcsclean would do without
actually doing it.
- -q[rev]
- Do not log the actions taken on standard output.
- -r[rev]
- This option has no effect other than specifying the
revision for comparison.
- -T
- Preserve the modification time on the RCS file even if the
RCS file changes because a lock is removed. This option can suppress
extensive recompilation caused by a make(1) dependency of some
other copy of the working file on the RCS file. Use this option with care;
it can suppress recompilation even when it is needed, i.e. when the lock
removal would mean a change to keyword strings in the other working
file.
- -u[rev]
- Unlock the revision if it is locked and no difference is
found.
- -V
- Print RCS's version number.
- -Vn
- Emulate RCS version n. See co(1) for
details.
- -xsuffixes
- Use suffixes to characterize RCS files. See
ci(1) for details.
- -zzone
- Use zone as the time zone for keyword substitution;
see co(1) for details.
EXAMPLES
rcsclean *.c *.h
removes all working files ending in
.c or
.h that were not changed
since their checkout.
rcsclean
removes all working files in the current directory that were not changed since
their checkout.
FILES
rcsclean accesses files much as
ci(1) does.
ENVIRONMENT
- RCSINIT
- options prepended to the argument list, separated by
spaces. A backslash escapes spaces within an option. The RCSINIT
options are prepended to the argument lists of most RCS commands. Useful
RCSINIT options include -q, -V, -x, and
-z.
DIAGNOSTICS
The exit status is zero if and only if all operations were successful. Missing
working files and RCS files are silently ignored.

BUGS
At least one
file must be given in older Unix versions that do not
provide the needed directory scanning operations.
