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 noth-
       ing.   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 work-
       ing  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 num-
       ber 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  rcsd-
       iff(1), which prints out the differences, and ci(1), which normally re-
       verts to the previous revision if a file was not changed.

OPTIONS
       -ksubst
              Use subst style keyword substitution when retrieving  the  revi-
              sion 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  actu-
              ally 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 sup-
              press 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 key-
              word 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.  Use-
              ful 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 us-
              ing standard i/o routines.  You can adjust the memory  limit  by
              setting  RCS_MEM_LIMIT to a numeric value lim (measured in kilo-
              bytes).  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 de-
              fault 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:

       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 pro-
       vide the needed directory scanning operations.
