RCSCLEAN(1)               USER COMMANDS               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 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 out­
     put.

     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 com­
     pared 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  revi­
          sions.   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.

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.
