logins | awk '{print $1}' | xargs -tn1 getprpw -m slogint

Top users taking space on home directories..

# du -sk /home/* | sort -n -r | more

Here's my favourite. It looks in the sulog for bad root attempts. I actually run this out of cron at defined periods, but just as easy from the command line.

# cat /var/adm/sulog | awk '$4 == "-" {print $0}' | grep 'root$'

(Try doing any of those in a GUI.....)

One I use a lot - show the most recently changed/created files in a directory:

ll -t | head -23

I make it an alias for "llast".
