Tim and others, The wiki would be a good place to keep a collaborative reference of tidbits you find handy and helpful as you go:
http://wiki.euglug.org/index.php/CommandLineTutorial is a good place to start, other pages, say for maintaining and revamping a system might be helpful too. ciao, Ben On Mon, 10 Nov 2003 21:52:31 -0600 Timothy Bolz <[EMAIL PROTECTED]> wrote: | Jamie | I tried the command nice. | | Can you delete the /var/log files and will they recreate themselves. | I was thinking /var/log might be taking up a bunch of space.
