Adding aliases, and altering user paths/variables

In this recipe, we are going to create an alias of a command and alter the user path variable. We are going to learn about the alias command. Using alias command, we are going to create aliases for other commands.

 

Getting ready

Besides having a terminal open, we need the basic knowledge of the alias command.

How to do it...

1. We will create a alias for the pwd command. Run this command:

$ alias p=pwd

2. Now, we will create an alias for the ls command. Run the following command:

$ alias l=”ls -l”

How it works...

The alias command is used to create a shortcut for commonly used commands.

1. We have created an alias p for command pwd. So, we just run the p command to get the present working directory.
2. We have created an alias l for command ls. So, we just run the l command to get the list.
