rcsclean [


] [



Although included with RCS, this command is optional and might not be installed on your system. rcsclean compares checked-out files against the corresponding latest revision or revision R (as given by the options). If no differences are found, the working file is removed. (Use rcsdiff to find differences.) rcsclean is useful in makefiles. For example, you could specify a "clean up" target to update your directories. rcsclean is also useful prior to running rcsfreeze . rcsclean accepts the standard options -q , -V , and -x .


-k c

When comparing revisions, expand keywords using style c . (See co for values of c .)

-n[ R ]

Show what would happen but don't actually execute.

-r[ R ]

Compare against revision R . R can be supplied as arguments to other options, so -r is redundant.

-u[ R ]

Unlock the revision if it's the same as the working file.


Remove unchanged copies of program and header files:

rcsclean *.c *.h
