Top sudo commands in Linux

In my previous article  I had described about the beauty of Linux/Unix operating system. In that series I had mentioned some feature of Linux/Unix operating system those were as follows:

• Easy to access both local and remote machine  (In my next article I will be writing about access of remote machine)
• Secure
• Less time consuming

To perform task either from one user to another user or local system to remote system, you  have to use commands. Because you can not go there to perform task by using mouse. But by using some commands you can login ($su user_name used to login from one user to another within a cluster and ssh command can be used to login a remote machine) in those systems from your system and your task can be done with help of commands.

Here,  we are writing some command which can be used by super /administrative /power user only. These commands are as follows:

• How to shutdown your computer

             $sudo poweroff

• How to restart your computer

            $sudo reboot

• How to update your computer system

            $sudo apt-get update

apt-get is the command line tool to work with APT software packages. Where APT stand for Advanced  Package Tool which is associated with Debin .deb software packaging system.

• How to install a software in your computer system ( only software which are avilable in your software center )

            $sudo apt-get install vim

In some packages you will be asked

In this step, system wants to know that whether you want to install (Y) or not (n)

Finally, if  you don’t use sudo in your command then you will come up with an error as follows

• How to remove a software from your computer

             $sudo apt-get remove vim
