sudo options

Use sudo -i to create an interactive root shell on CentOS. Instead of $, you will see #, indicating that you have root access. Very useful when you have to run a sequence of various commands which require root access. You won’t have to type sudo before each command.

Now on CentOS 7

Around 3 weeks ago,  I made a couple of big changes. Changed my MacBook Air for a Lenovo ideapad 320, and then installed CentOS 7.  Effectively, i’m starting again.
