Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

top svn committers (without awk)
list top committers (and number of their commits) of svn repository. in this example it counts revisions of current directory.

This is useful if you have a program which doesn't work well with multicore CPUs. With taskset you can set its CPU affinity to run on only one core.

Get DELL Warranty Information from support.dell.com
pretty much the same. I use awk rather than grep and perl. It looks like the URL has been updated. The service tag can also be retrieved via snmp - potential for a for loop over a list of servers. I might have a look into doing an example.

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

Show IP Address in prompt --> PS1 var
when working with many machines in a computer lab need to know the IP addr is very large, this is a simplistic solution to make things easier
