If you have ever found yourself editing a config file in vi and find out, when you go to write, that you forgot to edit as root and the file is read only to you. Try this vi command<br>

It is me. Not you.<br>
<br>
Many years ago I looked for SU and was advised to do all 'root' stuff with $ sudo.<br>
I did not know about $ sudo su<ENTER> until recently.<div><div><br>
