How to update Ubuntu terminal? [closed]

execute this in a terminal :

VIA APT-GET :

Using apt-get command line tool

apt-get is the command-line tool for handling packages. You can use following command options:

• apt-get update: Update is used to resynchronize the package index files from their sources via Internet.
• apt-get upgrade: Upgrade is used to install the newest versions of all packages currently installed on the system
• apt-get install package-name: install is followed by one or more packages desired for installation. If package is already installed it will try to update to latest version.

1. Open terminal and type following two commands (Application > Accessories > Terminal):

2. Get update software list, enter:

   sudo apt-get update
   

3. Update software(s) i.e. apply updates:

   sudo apt-get upgrade
   

I would use Synaptic if you're a beginner (I actually use apt-get but that's been covered above). Open Synaptic and search for the terminal program that you want to update. Check the box next to it and save your configuration. It's very easy to manage packages with Synaptic. Try things out and read the help files and you'll be an expert in no time.

Also, the Update Manager should run at startup and check for updates. You can run the update manager by itself and it will upgrade all of the packages on your system (or even upgrade to a new distribution).

Synaptic and Update Manager should give you what you need.
