[Ubuntu-BD] command??

[shiplu]

$ sudo apt-get install vlc
In the above command,
apt-get is the main command. Install is like subcommand. Vlc is the
parameter. Current user has no permission to execute that command. So
sudo comes in place. When any command is executed by sudo, the command
is actually executed by a super user who has the permission.
Suppose, a command ls. You can use it to see file listing of directory
where you have at permission. It will work on your home folder. But if
you issue the following command,
$ ls /home/otheruser/
It wont work. Coz you dont have permission to view others home folders
content. So you request a super user to do that by prepending sudo.
You do the following.
$ sudo ls /home/otheruser/
Here again ls is the main command. And /home/otheruser/ is the
parameter of ls. Though it does not contain any subcommand, but i hope
you understand it.
