Using Linux - Files and Directories

With the terminal you can create, copy, move, and delete files and directories. The following are the most important commands to do this.

• cd - change directory
• mkdir - make a new directory
• ls - list directory contents
• cp - copy files
• rm - remove files (be careful, there is no recycle bin or trash - once you delete, it's gone)
• rmdir - remove directory
• nano - simple text editor

And here is a transcript of the use of these commands on the CS server.
