Change prompt on command line?

Question

My prompt is quite verbose - which is good most of the time - but now I would like to switch it temporarily because I want to make a screen shot of the terminal. For that purpose I would prefer not to delve into config files but to set the prompt just quickly to something short like ">" and then restore it.

Is that possible with fish shell?

Answer 1

Do this:

1. funced fish_prompt

2. at the top of the function add the line

   echo '> '; return
   

   and save

3. screen capture
4. to restore your prompt, funced fish_prompt and remove the inserted line.

Answer 2

If you install oh-my-fish then you can switch themes quickly:

$ omf theme <installed_theme_name>

Here is an example:
