RCSCLEAN(1)                                                        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 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,  nor-
       mally 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 opera-
       tions.
