I have a few users with superuser cabability on an HP-UX 10.x environment. On various files in the /etc dir. I am using the Revision Control System (RCS). The individuals with Root privileges have a habit of editing a file without “checking it out” first. When using RCS you execute a command such as co -l and that locks the file from being edited. But the file being edited is overwritten at this point. So if someone adds a filesystem to the fstab file for instance, without usingRCS that filesystem is erased from fstab and the previously saved version in RCS is now current. I like RCS, but I need to keep users from editing files without using it. I thought there was a way I could alias this in vi but to this point I haven’t been able to find it. Any tips would be appreciated.
