[linux] How to edit a text file in my terminal

I'm using Linux mint and using the vi command to create text files, now that I created a text file and saved it. How do I get back into to edit the text file again?

vi helloWorld.txt

If you are still inside the vi editor, you might be in a different mode from the one you want. Hit ESC a couple of times (until it rings or flashes) and then "i" to enter INSERT mode or "a" to enter APPEND mode (they are the same, just start before or after current character).

If you are back at the command prompt, make sure you can locate the file, then navigate to that directory and perform the mentioned "vi helloWorld.txt". Once you are in the editor, you'll need to check the vi reference to know how to perform the editions you want (you may want to google "vi reference" or "vi cheat sheet").

Once the edition is done, hit ESC again, then type :wq to save your work or :q! to quit without saving.

For quick reference, here you have a text-based cheat sheet.

Try this command:

sudo gedit helloWorld.txt

it, will open up a text editor to edit your file.

OR

sudo nano helloWorld.txt

Here, you can edit your file in the terminal window.

You can open the file again using vi helloworld.txt and then use cat /path/your_file to view it.

Open the file again using vi. and then press " i " or press insert key ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!
