Installing Software on Ubuntu - Part 4 (Terminal)

Using terminal command line is the efficient way to install software on Ubuntu. The command line we will use is 'apt-get'. The command-line format of the apt-get command is:

sudo apt-get command

We precede the command with sudo because all software management requires root (administrator) powers. It’s always advisable to get the most up to date list from the software repositories. To do that, type the following command:

sudo apt-get update

To install software we will use the following command (eg: Abiword word processor) :

sudo apt-get install software_name

sudo apt-get install abiword

If any dependencies are required, apt-get lists them and asks whether you want to install them as well.
