01: The Unix Shell

Introduction to the Unix Shell

Check out the amazing shell lesson from Software Carpentry.

It's important to go through lessons 1-5 (6-7 can be done later). We suggest that you do the lessons in the following order:

1. Introducing the Shell: What is a command shell and why would I use one?
2. Navigating Files and Directories: How can I move around on my computer? How can I see what files and directories I have? How can I specify the location of a file or directory on my computer?
3. Working With Files and Directories: How can I create, copy, and delete files and directories? How can I edit files?
4. Pipes and Filters: How can I combine existing commands to do new things?
5. Finding Things: How can I find files? How can I find things in files?
6. Loops: How can I perform the same actions on many different files?
7. Shell Scripts: How can I save and re-use commands?
