Display Linux Commands using Python

There are hundreds of Linux commmand line commands out there. Here I will attempt to give you the most important basic ones. These commands can be typed at any terminal prompt . Note, many of them require you first be logged in as root (su) before you can issue them. I have placed them in alphabetical order using a MySql database. Please let me know, if you feel I have left out your favorite most used command, by clicking here.

Note, if you are familiar already with Linux or UNIX commands and want a good source for comparing the same command on various platforms (Linux, Solaris, HP-UX, MAC OSX, etc.), please go to the rosetta stone.
