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 cor-
responding 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 revi-
sion if a file was not changed.

OPTIONS
-ksubst
Use subst style keyword substitution when retrieving the revision for com-
parison. 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 operations.
