 As you start to use bash more often, you will find yourself using specific combinations of commands and flags to accomplish basic tasks. You can drastically cut the amount of typing you will do by setting **aliases**, which are just pseudo-commands that refer to other commands. These are the simplest customizations to make to bash. As you start to use bash more often, you will find yourself using specific combinations of commands and flags to accomplish basic tasks.

-For example, lets look at the ''ls'' command. The default output of ls is very bare-bones, and you have to type something like ''ls -lhaF'' to get a more detailed view. To make it so typing ''ls'' by itself gives you an easy-to-read detail view, add the following line to your **.bash_aliases** file:+For example, lets look at the ''ls'' command.

 Aliases do not have to be permanent, either. To set that same alias to only work for the current shell session, you would run: Aliases do not have to be permanent, either. To set that same alias to only work for the current shell session, you would run:
