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 noth-
       ing.   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 work-
       ing  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 num-
       ber 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	 rcsd-
       iff(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	 revi-
	      sion 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	 actu-
	      ally 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 sup-
	      press 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 key-
	      word 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.  Use-
	      ful 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 pro-
       vide the	needed directory scanning operations.
