RCSCLEAN(1)         UNIX Programmer's 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 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 oth-
     ers 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.

     RCSLOCALID
          Local keyword to substitute. See co(1) for details.

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.
