rcsclean - clean up working files
rcsclean [options] [ file ... ]
rcsclean removes working files that were checked out and never modi‐
fied. 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
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 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
asks whether to check in a file if it 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
Unlock the revision if it is locked and no difference is found.
-Vn Emulate RCS version n. See co(1) for details.
Use suffixes to characterize RCS files. See ci(1) for details.
rcsclean *.c *.h

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, and -x.
The exit status is zero if and only if all operations were successful.
Missing working files and RCS files are silently ignored.
