How to install packages (software) in Ubuntu/Debian using command line.

Command line is an easy way of installing the softwares on GNU/Linux. Some students come to me and ask for package installation method on Ubuntu. So I just thought of writing few lines on it.

First of all, you must know, most of the packages that will be used on Ubuntu are provided by Ubuntu website itself.
So update the list of the packages. Open the terminal and run the following command.

$ sudo apt-get update

then search a package in the list

$ sudo apt-cache search vlc

.
.

vlc - multimedia player and streamer

Now install the packages

$ sudo apt-get install vlc
