rcsclean - clean up working files
rcsclean [options] [file...]
Use subst style keyword substitution when retrieving the
revision for comparison. See co(1) for details. Do not
actually remove any files or unlock any revisions. Using
this option will tell you what rcsclean would do without
actually doing it. Do not log the actions taken on standard
output. This option has no effect other than specifying
the revision for comparison. Unlock the revision if
it is locked and no difference is found. Emulate RCS version
n. See co(1) for details. Use suffixes to characterize
RCS files. See ci(1) for details.
rcsclean removes working files that were checked out and
never modified. 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.
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. Names
are paired as explained in ci(1).
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 asks whether to check in a file if
it was not changed.
At least one file must be given in older Unix versions
that do not provide the needed directory scanning operations.
rcsclean *.c *.h
removes all working files ending in or that were not
changed since their checkout. rcsclean
removes all working files in the current directory that
were not changed since their checkout.
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,
and -x.
The exit status is zero if and only if all operations were
successful. Missing working files and RCS files are
silently ignored.
rcsclean accesses files much as ci(1) does.
