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.

rcsdiff(1),
which prints out the differences,
and
ci(1),
which
normally reverts to the previous revision
if a file was not changed.
