NAME
rcsclean - clean up working files
SYNOPSIS
rcsclean [options] [file...]
OPTIONS
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.
DESCRIPTION
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.
RESTRICTIONS
At least one file must be given in older Unix versions that do not provide the needed directory scanning operations.
EXAMPLES
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.
ENVIRONMENT
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.
DIAGNOSTICS
The exit status is zero if and only if all operations were successful. Missing working files and RCS files are silently ignored.
FILES
rcsclean accesses files much as ci(1) does.
