This is how you make a permanent alias in Ubuntu Linux with these simple terminal commands.

Method 1

Open file ~/.bashrc  with your favorite editor. lets say we use Visual Code for example or Nano:

Visual Code:

$ code ~/.bashrc

Nano:

$ nano ~/.bashrc

Add teh following line at the end and save:

alias sail="./vendor/bin/sail"

Now save the changes:

$ source ~/.bashrc

Method 2

Alternately, you can create an alias files, notice in the ~/.bashrc you will see this code below:

$ nano ~/.bash_aliases

All you have to do is create the file or if you already have it edit and add the following line

alias sail="./vendor/bin/sail"

Save the changes and then send the source command to activate the new alias into your system

source ~/.bash_aliases

Thats it.
