Hi, it's been a few years since I played with a Solaris box. I would look at your history settings, I suspect that if the history file reaches the maximum that you chose, it will automatically clear itself. Now what I cannot remember is if it really "wipes" it or just archives it to another file.

Try Google for "Solaris" and "History" and "Archive"...................if that doesn't work PM me ........it is Sunday and I foolishly gave all the slaves who would know the answer the day off to worship

Errr..... like my mates won't be back at work until monday

What version of Solaris by the way?
