rcsclean - clean up working files
rcsclean [options] [ file
... ]
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 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 suffix denote 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.
- -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 file even if the 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 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 's version number.
- -Vn
- Emulate version n. See co(1)
for details.
- -xsuffixes
- Use suffixes to characterize files. See ci(1)
for details.
- -zzone
- Use zone
as the time zone for keyword substitution; see co(1)
for details.
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.
rcsclean accesses
files much as ci(1)
does.
- 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 commands. Useful
RCSINIT
options include -q, -V, -x, and -z.
The exit status is zero
if and only if all operations were successful. Missing working files and
files are silently ignored.

At least one file must be given in older
Unix versions that do not provide the needed directory scanning operations.
