NAME
       rcsclean - clean up working files

SYNOPSIS
       rcsclean [options] [file...]

OPTIONS
       Use  subst  style keyword substitution when retrieving the revision for
       comparison. See co(1) for details.  Do not actually remove any files or
       unlock  any  revisions.	 Using this option will tell you what rcsclean
       would do without actually doing it.  Do not log the  actions  taken  on
       standard	 output.   This option has no effect other than specifying the
       revision for comparison.	 Unlock the revision if it is  locked  and  no
       difference  is  found.	Emulate	 RCS version n. See co(1) for details.
       Use suffixes to characterize RCS files. See ci(1) for details.

DESCRIPTION
       rcsclean removes working files that were checked out  and  never	 modi‐
       fied.  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.

       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. Names are paired as explained in ci(1).

       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 asks
       whether to check in a file if it was not changed.

RESTRICTIONS
       At least one file must be given in older Unix versions that do not pro‐
       vide the needed directory scanning operations.

EXAMPLES
       rcsclean	 *.c  *.h

       removes	all  working  files  ending  in or that were not changed since
       their checkout.	rcsclean

       removes all working files  in  the  current  directory  that  were  not
       changed since their checkout.

ENVIRONMENT
       options	prepended  to the argument list, separated by spaces.  A back‐
       slash  escapes  spaces  within  an  option.  The	 RCSINIT  options  are
       prepended  to  the  argument lists of most RCS commands. Useful RCSINIT
       options include -q, -V, and -x.

DIAGNOSTICS
       The exit status is zero if and only if all operations were  successful.
       Missing working files and RCS files are silently ignored.

FILES
       rcsclean accesses files much as ci(1) does.
