NAME

       rcsclean - clean up working files

SYNOPSIS

       rcsclean [options] [ file ... ]

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.  Filenames 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.   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 RCS'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.

       -zzone Use zone as the time zone for keyword substitution; see co(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, -x, and -z.

       RCS_MEM_LIMIT
              Normally, for speed, commands either memory map or copy into memory the RCS file if  its  size  is
              less  than  the  memory-limit,  currently  defaulting  to  ``unlimited''.   Otherwise  (or  if the
              initially-tried speedy ways fail), the commands fall back to using standard i/o routines.  You can
              adjust  the  memory limit by setting RCS_MEM_LIMIT to a numeric value lim (measured in kilobytes).
              An empty value is silently ignored.  As a side effect, specifying RCS_MEM_LIMIT inhibits fall-back
              to slower routines.

       TMPDIR Name of the temporary directory.  If not set, the environment variables TMP and TEMP are inspected
              instead and the first value found is taken; if none of them are set, a host-dependent  default  is
              used, typically /tmp.

DIAGNOSTICS

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

       The  full  documentation  for RCS is maintained as a Texinfo manual.  If the info(1) and RCS programs are
       properly installed at your site, the command

              info rcs

       should give you access to the complete manual.  Additionally, the RCS homepage:

              http://www.gnu.org/software/rcs/

       has news and links to the latest release, development site, etc.

BUGS

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