1 Keep a list of commandsIndex
This is a list of basic Unix/Linux command names used in this course and the week number in which they were first introduced and described. A missing week number means the command hasn’t been formally introduced yet. All these command names have manual pages (though some of them are built-in to the shell and are described in the man page for the bash shell, e.g. exit is described deep inside the man page “man bash”).
Keep a notebook with these command names in it; you will be required to learn and remember at least some of what each of these commands can do:
