While I was referring to usage of SOURCE in linux, I got to know that from here source executes the command in current shell and "./" will execute in new shell.

My question is how do we know in which shell the commands are getting executed ?

  • The confusion arise when I saw the terms current shell and new shell. I am just checking how to check the current and new shell. May be the same query could be posted in different way.

Most (if not all) shells on Linux provide you with the $SHELL environment variable:

mtak@frisbee:~$ echo $SHELL
/bin/bash

It's still a better practice to run with ./ and provide a shell in the script you're running (that's in the first line starting with #!). This way you get more consistent results.
