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 standard output.
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 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 differences, and ci(1), which normally reverts to the previous revision if a file was not changed.
