rcsfreeze(1)rcsfreeze(1)NAME
rcsfreeze - freeze a configuration of sources checked in under RCS
SYNOPSIS
rcsfreeze [name]
DESCRIPTION
rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration.
The idea is to run rcsfreeze each time a new version is checked in. A unique symbolic name (C_number, where number is increased each time
rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.
An optional name argument to rcsfreeze gives a symbolic name to the configuration. The unique identifier is still generated and is listed
in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.
A log message is requested from the user for future reference.
The shell script works only on all RCS files at one time. All changed files must be checked in already. Run rcsclean(1) first and see
whether any sources remain in the current directory.
RESTRICTIONS
rcsfreeze does not check whether any sources are checked out and modified.
Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands.
Error checking is rudimentary.
rcsfreeze is just an optional example shell script, and should not be taken too seriously. See CVS for a more complete solution.
FILES
version number log messages, most recent first

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.
-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.
