NAME
rcsclean - clean up working files
SYNOPSIS
rcsclean
[options] [ file ... ]
DESCRIPTION
rcsclean
removes working files that were checked out and never modified.
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.
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.
Names are paired as explained in
ci(1).
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 asks whether to check in a file
if it 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.
- -u[rev]
-
Unlock the revision if it is locked and no difference is found.
- -Vn
-
Emulate RCS version
n.
See
co(1)
for details.
- -xsuffixes
-
Use
suffixes
to characterize RCS files.
See
ci(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,
and
-x.
DIAGNOSTICS
The exit status is zero if and only if all operations were successful.
Missing working files and RCS files are silently ignored.

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