|−|Here is an example session from running on the CS server using all of these commands . Note that the part "cs299@cs:~> " is a prompt that is printed by the terminal, and the part after this is what was typed by the user. So for the first command, the user typed the command uptime and then pressed enter. The system then printed some information on the next line, and then printed the prompt "cs299@cs:~> " again to indicate it is ready for the next command. The prompt displays "cs299" because that is the user that was logged in running these commands. If your username was "cs15115" then your prompt would be something like "cs15115@cs:~>". |+|

This page is a part of the Linux and CS Systems - Getting Started. This page assumes you have your computer setup to connect to the CS server, or have the appropriate software installed on your computer to run commands. Go back to the Linux and CS Systems Getting Started main page if you don't have our system setup yet.
The following are some commands to print information about the system.
- uptime - how long since last system reboot
- df - information about disk free space
- whoami - which user is currently logged in on the terminal
- hostname - what computer are you currently running commands on
- pwd - which directory are you inside of
- clear - clear the terminal screen
- finger - see which other users are currently logged in
- man - help about a command (manual). While using man - use q key to quit, and up/down arrows to scroll.
The following is a transcript of the commands and screen output from the youtube video linked at the top of this page. Blank lines have been put in after each command. You can read through the transcript and think about what you think the output will be after each command is entered, and check that this is how it shows in the transcript.
Note that the transcript is for the user cs15100 logged in to the CS server.
