system rcspurge - delete versions of RCS files in a system
configuration or a part of it.
system rcspurge [options] system_path [files]
The command system rcspurge removes specified versions from RCS
libraries placed in a system configuration or in a part of it. If a
RCS library is defined as a symbolic link to a library from another
configuration, the files are not purged.
Specifies a system configuration or a subsystem in a system
configuration as a top of directory tree where the attributes
will be defined.
Specifies files which versions should be deleted. If no file is
specified then all the files placed in every RCS library in the
directory tree are looked for, i.e. the default value for files
is RCS/* for each subsystem.
-q Quiet mode. Diagnostics are not printed.
-nt Do not apply the command on the complete directory tree, but only
on the directory specified with system_path.
Delete versions of all files belonging to the group grp.
Delete the versions given by range. A range of the form rev1:rev2
means the versions between rev1 to rev2 on the same branch, :rev
means from the beginning of the branch containing rev up to rev,
and rev: means from version rev to the end of the branch. None of
the outdated versions may have locks. If neither -r, -kr nor -ks
is specified then the latest version of a file is kept.
Delete all the versions but that one specified by rev.
Note, if rev is a version in a branch, only other versions in
this branch will be removed. All other branches, and the main
trunk will be kept as before.
Delete all the versions but those that have the state status. If
more than one status should be kept, state is a list of statuses,
separated by commas.
Select files specified by the suffixes for RCS files. A nonempty
suffix matches any pathname ending in the suffix. An empty suffix
matches any pathname of the form RCS/file or path/RCS/file. The
-x option can specify a list of suffixes separated by /. For
example, -x ,v/ specifies two suffixes: ,v and the empty suffix.
If two or more suffixes are specified, they are tried in order
when looking for an RCS file; the first one that works is used
for that file. If no RCS file is found but an RCS file can be
created, the suffixes are tried in order to determine the new RCS
file's name. The default for suffixes is installation-dependent;
normally it is ,v/ for hosts like Unix that permit commas in file
names, and is empty (i.e. just the empty suffix) for other hosts.
system rcspurge -ksRel,Stable
deletes all the versions of files, except those that have the statuses
Rel or Stable.
