Has it happened to you before that - you run a command and forgot to 'sudo' - and hence the commnd fails and now you need to re-run the command all over again? Well in that case this is how you can save some time.
[debu@DebaTestBox ~]$ sudo !!
Forgot 'sudo' before editing a file:
Believe me this is the most frustrating one, and it happens to me a lot to me. You edited quite a few in the file and when try to save&xit( :wq!) you see an error as below
E212: Can't open file for writing
Press ENTER or type command to continue
Well, the below is a savior un this kind of scenario
:w !sudo tee %
this will ask your password the there in, and you are done. All your edits are now recorded by Vim editor.
Cheers!!!
Hope it helps!
