% Unix/Linux Command List You Must Know (Weekly Cumulative) % Ian! D. Allen - - [www.idallen.com] % Winter 2017 - January to April 2017 - Updated 2017-05-30 03:27 EDT - [Course Home Page] - [Course Outline] - [All Weeks] - [Plain Text] Unix/Linux Command List You Must Know (Weekly Cumulative) ========================================================= This is a list of Unix/Linux command names used in this course and (eventually) the week number in which they were first introduced and described. A missing week number means the command hasn't been formally introduced yet. This page is updated weekly as new commands are introduced. Almost all these command names have manual pages. Command names that are built-in to the shell (e.g. `cd`, `exit`, `pwd`, `history`, etc.) are described somewhere in the man page for the `bash` shell and you can also use the BASH shell built-in `help` command to get information about built-in commands, e.g. `help help` and `help pwd`, etc. > This list only gives the names of the commands, not what the commands do or > how to use them. As each command is introduced, you must keep your own > notebook with these command names in it and a short description of what > each command does; you will be required to learn and remember at least some > of what each of these commands can do. Solutions to assignments in this course use only these command names. If you want to use other command names, clear it with your instructor first.
