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.  Pathnames 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.

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.
