If you do command line work under Linux, you probably are aware that when pressing <TAB>
automatically completes your
command, or give you options for it that are currently available. For instance, when entering cd l
en pressing <TAB>
,
bash gives you a list of all directories starting with an l
, which you can select instead of type. If there is only
one available directory that starts with an l
, it will automatically fill this in for you.
A great way to speed up your CLI development work, and an even better way to get acquainted with all options that are available to you for certain applications.
