rcsclean - clean up working files
rcsclean [options] [ file ... ]
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 out- put. 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 oth- ers denote working files. The number of the revision to which the working file is com- pared 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.
-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 revi- sions. 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 GNU 1993/11/03 1 RCSCLEAN(1) UNIX Programmer's Manual RCSCLEAN(1) 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.
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.
rcsclean accesses files much as ci(1) does.
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. RCSLOCALID Local keyword to substitute. See co(1) for details. GNU 1993/11/03 2 RCSCLEAN(1) UNIX Programmer's Manual RCSCLEAN(1)
The exit status is zero if and only if all operations were successful. Missing working files and RCS files are silently ignored.

At least one file must be given in older Unix versions that do not provide the needed directory scanning operations. GNU 1993/11/03 3
