NAME
       rcsclean - clean up working files

SYNOPSIS
       rcsclean [options] [ file ... ]

DESCRIPTION
       rcsclean removes working files that were checked out and
       never modified.  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.

OPTIONS
       -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
              revisions.  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
              revision for comparison.

       -T     Preserve the modification time on the RCS file even
              if the RCS file changes because a lock is removed.

RCSCLEAN(1)                                           RCSCLEAN(1)


              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 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.

EXAMPLES
              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.

FILES
       rcsclean accesses files much as ci(1) does.

ENVIRONMENT
       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, and -x.

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

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