       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
       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.

              Use subst style keyword substitution when retrieving the
              revision 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
              actually 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
              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.

              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)
              for details.

              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.
              Useful 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.

       At least one file must be given in older Unix versions that do not
       provide the needed directory scanning operations.
