 | Clearing the screen There are times when you will need or want to clear your screen. Surprisingly, the clear command will accomplish this task for you. |
| Displaying system information If you would like to know information about the system you are working on, you can use both the hostname and uname command. The hostname command, as its name implies, will tell you the system's host name. The uname command will print different pieces of system information such as the operating system, the operating system version, the hostname, the host processor type, and more. |
| Printing text to the display The echo command is used to print a line of text to your display. This sounds like a simple and rather useless command, but you will see its usefulness as you become more familiar with the UNIX or Linux operating system. |
