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. Filenames 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 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.
