OK, this error has been in the shells for a long time. If you bring up a new window, or just a shell as a regular user, and then type 'history' you see what you should expect, one line with the history command. If you now do a su, and become root, and then do the same 'history' command you will see several hundred lines of history from who knows how many previous sessions as root. If you bring up a second window, and become root there too, doing the 'history' command will show the same -history- as the first (sigh) Shouldn't these things be truncated when the root shell closes down? I don't see any security problems here, but it is a real pain in the ass. -- Reg.Clemens reg@xxxxxxx
