Install full function of file editor in ubuntu.
I install ubuntu and try to edit the text likes on centOS but all shortcut key is not working properly, why that so, then I found default install vim is not full package.
Ubuntu default vim editor doesn't have full function of text edit. So we need to install extra packages to work it smoothely. For that go to the console and type the following command
jay@jay-vm:~$ sudo apt-get install vim
[sudo] password for jay
The output screen may show files to be downloaded just type Yes
Now you have full function vim editor. Every shortcut key must work.
