In the following:

[09:15:22] /tools # pwd
/tools
[09:15:23] /tools # echo foo
foo
[09:15:27] /tools #

I want to read everything preceding the "#" (I'll call it the signature for now). The signature is auto-filled by the shell on every line where a user can input text.

I tried looking through uname without luck, and I've spent a good deal of time trying to find the proper name for this "signature" without success. Is there a way to do this (or, does anyone know the correct name for what I'm trying to read)?

That's called a *prompt*. It *prompts* the user for input. – Ken White Jun 12 '19 at 23:47

From https://stackoverflow.com/questions/22322879/how-to-print-current-bash-prompt basically do this: `echo "'${PS1@P}'"` – Perplexabot Jun 12 '19 at 23:55

My question looks to be a duplicate. Thanks for your clarification! – Poseidon Online Jun 13 '19 at 00:02
