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
For each file given, rcsclean compares the working file and a revision
in the corresponding RCS file. If it finds a difference, it does noth‐
ing. 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 work‐
ing 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 num‐
ber 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 rcsd‐
iff(1), which prints out the differences, and ci(1), which normally
reverts to the previous revision if a file was not changed.
Use subst style keyword substitution when retrieving the revi‐
sion 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 actu‐
ally doing it.
Do not log the actions taken on standard output.
This option has no effect other than specifying the revision for
-T Preserve the modification time on the RCS file even if the RCS
file changes because a lock is removed. This option can sup‐
press 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 key‐
word strings in the other working file.
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.
Use suffixes to characterize RCS files. See ci(1) for details.
-zzone Use zone as the time zone for keyword substitution; see co(1)
rcsclean *.c *.h
removes all working files ending in .c or .h that were not changed
since their checkout.
removes all working files in the current directory that were not
changed since their checkout.
rcsclean accesses files much as ci(1) does.
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. Use‐
ful RCSINIT options include -q, -V, -x, and -z.
The exit status is zero if and only if all operations were successful.
Missing working files and RCS files are silently ignored.
