Checking out a read-only file under RCS
When you are through modifying your file for the moment, you can check out a "read-only" copy of your file, that is, a copy without write permissions (so no one can modify it) and also with the latest version numbers in its ID keywords (see `Adding ID keywords in an RCS file').
co command to check out a read-only file. For
example, to check out file
% co foo RCS/foo,v --> foo revision 1.2 doneOnce you have done this, your file will exist in its original location, but without write permissions (see `What are permissions?').
If you want to modify the file, use the normal procedure for locking a file. This procedure will overwrite the read-only copy with a writeable working copy; see `Locking a file under RCS control'.
