re-assign line numbers

Remove any RPMs matching a pattern
This should be an option to rpm, but isn't. I wind up using it a lot because I always forget the full name of the packages I want to delete.

Scan for [samba|lanman] NetBIOS names and ip addresses in LAN by ARP.

make sure you don't add large file to your repository

Load average + API google chart
limite = threshold

Display information sent by browser
Have netcat listen on port 8000, point browser to http://localhost:8000/ and you see the information sent. netcat terminates as soon as your browser disconnects. I tested this command on my Fedora box but linuxrawkstar pointed out that he needs to use $ nc -l -p 8000 instead. This depends on the netcat version you use. The additional '-p' is required by GNU netcat that for example is used by Debian but not by the OpenBSD netcat port used by my Fedora system.

delete PBS jobs based on strings from qstat output

Find duplicate UID in /etc/passwd
You can use only awk

Colour part of your prompt red to indicate an error
If the return code from the last command was greater than zero, colour part of your prompt red. The commands give a prompt like this: [user current_directory]$ After an error, the "[user" part is automatically coloured red. Tested using bash on xterm and terminal. Place in your .bashrc or .bash_profile.

du and sort to find the biggest directories in defined filesystem
I had the problem that our monitoring showed that the "/" filesystem is >90% full. This command helped me to find out fast which subdirs are the biggest. The system has many NFS-mounts therefore the -x.
