RCSCLEAN(1)                     GNU(1992/04/10)                     RCSCLEAN(1)


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.

      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 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 asks whether
      to check in a file if it 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.

      -u[rev]
            Unlock the revision if it is locked and no difference is found.

      -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.
