Linux sysadmin toolbox..
This article from enterprise.linux.com is the second on those essential linux command line utilities for system administrators. Covered this time around are netcat, tcpdump, ethereal, nmap, MultiTail, find Xargs, awk and sed, bash and cvs. I’ve never used MultiTail, but it sounds like it’s worth looking at. Nmap is virtually essential in network auditing. Sed is one of those utitilies that it seems you can do most anything with.
I used to make use of locate until I discovered the find command. Find let’s you do so much more than just find a file by name, but by size greater than x amount, or newer than a certain time. It’s truly a powerful utility. CVS is mentioned as a way for keeping track of config file changes. Some have used it to keep their home directories backed up. (A good way to roll back a change.)
Anyway, if they’re not in your sysadmin toolkit, maybe they should be?
