I pretty much live on the Linux command line. There’s a number of tools I have in my ‘toolkit’ that I use on a daily basis to automate tasks, manage systems and provide features.
apt-get is one of the most important tools to understand if you’re using an Ubuntu distribution.
apt-get is like the Apple App Store, except it’s been around for much longer and everything it provides is absolutely free. When I’m setting up a new Linux machine I immediately download and install several useful packages.
$ sudo apt-get install ipython
$ sudo apt-get install nmap
$ sudo apt-get install mercurial
and so on. Very quickly your new Linux machine can be a database server, a graphic design workstation, or a development engine.
