RCSCLEAN(1)                            General Commands Manual                           RCSCLEAN(1)



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 revi‐
       sion 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  cur‐
       rent  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 check‐
       out.

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

ENVIRONMENT
       RCSINIT
              Options prepended to the argument list, separated by spaces.  A backslash escapes spa‐
              ces 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''.  Other‐
              wise (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  direc‐
       tory scanning operations.
