The Open Source U

One of the most difficult aspects of starting to use Linux– a server distribution in particular — is remembering all of the different command line programs that exist in order to aid your work.

Obviously, man is a great reference but that is actually difficult to use when getting started as it itself is a command line program. I was searching for a command to list all of the users on a system (I found it and will post a brief article on that soon) and I stumbled across this, so I wanted to share it (as well as retain it for future reference.)

This covers such things as:

• Networking information / status (arp, ifconfig, netstat, etc)
• File system information (df)
• Disk Size / utilization information (du)
• How to search for files with find
• Easy-to-use console text editors (nano, joe)
• Process management / information (ps, top)

In addition to listing the commands, it lists common usage scenarios and command line flags of note.
