This page provides some basic instructions for using the command line interface on Linux computers in CSIL, the Computing Science Instructional Labs at SFU, followed by a set of links to books and sites with more extensive tutorials. As they vary in detail, method and approach, try another one if the first one you try is not a good fit for you at this time. Suggestions and corrections are welcome (email us please). This page is aimed at new Linux users. CMPT 127 students may be particularly interested.
We assume:
What Am I Doing? What is Going On?
You are learning a different way to interact with a computer, working at the command line. It means typing commands at a prompt - no mouse. Typing only! Why?
What is Linux - what is an operating system for that matter?
Most computers need to run an "operating system" or OS to be usable. An OS is a computer program that performs tasks like running other programs (word processors, web browsers, C compilers...), opening and reading or writing files to storage, managing communication with other computers over a network, getting your input of mouse actions and typing to the program they are meant for, and getting the output of that program where it is supposed to go.
Linux is an operating system, Microsoft's Windows is an operating system, Apple's OS X is an operating system. They all have many fans and haters but given all the computer users who aren't in computing science - clearly you don't need to know much about operating systems to use a computer, and the same goes for taking CMPT 127. You will learn more about them in CMPT 300!
Many kinds of Linux are available, called distributions or distros; which also each has many fans and haters. CSIL uses a popular Linux distro called Ubuntu, but the basic command line work is nearly the same in all distros.
Step 1: Login, get that command line prompt
If you are an SFU Computing Science student, you can login with your SFU Computing ID (aka campus userid) and password to a Linux workstation in CSIL Burnaby or Surrey. You need card access to enter CSIL. We describe three ways to access CSIL Linux systems for practice and/or course work:
Get a Linux command line from a CSIL Linux workstation:
Once you are login, "Applications" and "Places" will be in the upper left of the screen. Use the mouse to get a terminal window with the prompt. Click the image for a close up if it helps:
1. Click on Applications to see its drop down menu...
2. ... on that menu click on Utilities to get a side menu...
3. ... scroll down on the side menu to "Terminal" and click on that.
A terminal window opens, a prompt is displayed. Use the mouse to grow the terminal window a bit:
Now, you can start typing in your Linux commands.

Now you can move on to one of these extra resources for further study:
