如何确定运行bash shell的解释器？

Question

I was working on this tutorial here and I want to know the path so I can put it in my shell scripts on the top line as is good practice.

I was told this is not accurate:

echo "$SHELL"

What is the correct way to determine the path to the interpreter for shell scripts?

This is a shared hosting account and it is not obvious where it is located.

This is a follow up to a similar but not duplicate here .

Answer 1

You can use

which -a bash

to list all paths for the current user that point to a bash program.
