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 stan-dard standard
dard output.
Files are paired as explained in ci(1). If no file is given, all working files in the current direc-tory directory
tory 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 differ-ences, differences,
ences, 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 sup-press suppress
press 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 com-mands. commands.
mands. 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 scan-ning scanning
ning operations.
