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  retriev-
              ing  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
              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 differ-
              ence 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  opera-
       tions.
