It’s been a long time since I’ve posted, but it’s been a really busy period..
On to the topic, using a feature such as aliases in a terminal, certainly makes you do things faster.
(To get an intro to aliases and a guide on how to save them permanently, read this)
So I’ve gathered some of mine and uploaded them at Github as a bash-aliases repo.
Here are some:
alias c='clear' # also, Ctrl + L works nicely
alias ls='ls -l --color=auto' # list files, colored output
alias agi='sudo apt-get install'
Append them over to your ~/.bash_aliases file
