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.
FILES
RCS/.rcsfreeze.ver version number RCS/.rcsfreeze.log log messages, most recent first
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. RCS_MEM_LIMIT An integer lim, measured in kilobytes, specifying the threshold under which commands will try to use memory-based operations for processing the RCS file. (For RCS files of size lim kilobytes or greater, RCS will use the slower standard input/output routines.) Default value is 256. TMPDIR Name of the temporary directory. If not set, the environment variables TMP and TEMP are inspected instead and the first value found is taken; if none of them are set, a host-dependent default is used, typically /tmp.

BUGS
rcsfreeze does not check whether any sources are checked out and modified. Although both working 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. GNU RCS 5.9.0 2014-06-10 RCSFREEZE(1)
