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.
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, 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.
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.
