Question

I am currently following a tutorial that asked to open a file with "sudo vi /..." first and formost I have half an understanding of how to type but I managed and now I need to save the file but how do I do that? I tried to use ctrl x but that doesnt work and there is no other means in the file/ edit section of the terminal. Please help.

Answer 1

To save, press:

:w

That is, the 'colon' key, then the 'w' key. Then the enter key.

To save and quit, hold the shift key, and hit 'z' twice.

To quit without saving, hit:

:q!

Then the enter key.
