Intro
This will be a short-and-sweet one. What is an alias you ask? It’s a shorthand version (macro) pretty much. Welp, let’s use it for something. Essentially, let’s goof off with it, for starters. Instead of using sudo
, let’s go with something more … well fun.
Here’s the obligatory screenshot:

sudo
Guide
Step 1.
Open ~/.bashrc
with your favourite text editor (nano, vim …)
Step 2.
At the very bottom of the file, add your alias in the following format:
alias='command'
Here’s mine:

Step 3.
Save the file and load the script, by running the following command:
source ~/.bashrc
And you’re done. I’m using this as a goof, but you can map seriously heafty commands to an alias, and you can make your life easier.
A more usable example
PHPCS is an amazing tool for checking code quality, if you’ve never heard of it check it out here: https://github.com/squizlabs/PHP_CodeSniffer
The command to check for PSR compliance is lengthy, and I really don’t want to type it out every time, so let’s make an alias of it.
Base command:
php phpcs.phar
-p
-n
-d memory_limit=320M
--standard="${STANDARD}"
--extensions=php,phtml
--runtime-set testVersion "${PHP_VER}" app
Mapped as an alias (inside the bashrc
file:

The above line is callable with psrcompliance
from the terminal
Great stuff, have fun!
