[file] 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, but I do not know how to edit this file and then save the edit. How do you do that?

The answer is


Open the file using vi or nano. and then press " i " ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!

Within Nano use Ctrl+O to save and Ctrl+X to exit if you were wondering


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
  1. 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.


For editing use

vi galfit.feedme //if user has file editing permissions

or

sudo vi galfit.feedme //if user doesn't have file editing permissions

For inserting

Press i //Do required editing

For exiting

Press Esc

    :wq //for exiting and saving
    :q! //for exiting without saving
