How to edit/save a file through Ubuntu Terminal

This is quite a simple question:

I just need to open a file (this filename is galfit.feedme). I can view the file with view galfit.feedme when I\'m in the directory

Answer 1

If you are not root user then, use following commands:

There are two ways to do it -

1.

sudo vi path_to_file/file_name

Press Esc and then type below respectively

:wq //save and exit
:q! //exit without saving

2. sudo nano path_to_file/file_name

When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.
