Linux aliases

You can create aliases to your linux system by editing file:

~/.bash_aliases

Update aliases by running:

sudo apt-get update

For example if you install composer:

curl -sS https://getcomposer.org/installer | php

https://getcomposer.org/download/

You can then create alias for composer by editing the bash file and typing:

alias composer='/usr/local/bin/composer'

Now you can run composer anywhere just by typing composer
