How to Create Linux Command Line with Bash Aliases

If you’ve never created an alias before, create a file called .bash_aliases in your $HOME path if it doesn’t exist yet.

Open a terminal and make sure that you are located in the $HOME directory.

$ cd ~

Create the .bash_aliases file

$ touch .bash_aliases

Everything inside .bash_aliases will be run because of the following code inside .bashrc

# You may want to put all your additions into a separate file like  

# ~/.bash_aliases, instead of adding them here directly.  

# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then  

. ~/.bash_aliases  

fi

Step 2 — Adding your own commands.

Now we can open the .bash_aliases file. And start adding our own custom commands!

You could edit the file with nano inside your terminal:

$ nano .bash_aliases

Or with a graphical text editor:

$ gedit .bash_aliases

Creating an alias.

Inside the file you can add your own custom commands:

alias testcommand='echo "waiting 3 seconds…"; sleep 3; echo "It worked!!"'

This is just an example command. You can basically do whatever you want in here, to make things more convenient for yourself.
