Reading user's PS1 from Swift command-line tool

Is it possible to extract the user's PS1 from the environment in a Swift script, so that I can replicate their prompt?

I left a note for myself a few years ago saying that it "disappears from the environment in the context of the script", but I figured it would be useful to ask.

(I'm aware that this question won't necessarily work between shells, but assume that I only care about bash. Furthermore, I know I can't necessarily interpret everything in a user's prompt, but I would like to get it).

Solution

  • Try this in Swift script :

    bash -i -c 'echo "$PS1"'
