Apt-get Command

apt-get is the command-line tool for working with APT software packages.


One of the first things  to do after the Ubuntu installation  is to use apt-get update and apt-get upgrade. Now, you might be aware of a few commands and their usage but perhaps you might not be aware of other apt-get commands and their usage.

There are two main tool around it: apt-get and apt-cache. apt-get is for installing, upgrading and cleaning packages while apt-cache is used for finding new packages. We’ll see all these commands with examples later in this guide.

Why we need to update package database with apt-get

apt-get basically works on a database of available packages. If you don’t update this database, the system won’t know if there are newer packages available or not. In fact, this is the first command you need to run in any Linux system after a fresh install.

For that we will use "sudo" to get to the root

Run this command periodically to make sure your source list is up-to-date. 

This command upgrades all installed packages. This is the equivalent of "Mark all upgrades" in Synaptic.

To install specific package

To un-install software packages without removing their configuration files (for later re-use the same configuration).

• Each package has a name and a description. This command lists packages whose name or description contains <search_term>.In this case we will use file as an example

In man apt-get we can get a full description of apt-get command

Now we learn how to move  in the root and install ,update and remove your computer using apt-get Ubuntu commands.If this was useful , please click like..
