Sorry ignore my question. Just watching a few seconds more gave me the answer. It is at the kernel level as you said. I never knew that before!

linuxmq says:

Very nice videos.
Something that I never understood. Why "#!/bin/bash" is so important in the first line of a script if the "#" starts a "comment line" that is "ignored"?
What is the process behind the scripting language that requires that specific line? I would understand if there wasn't any "#" first.
