If C is your "get stuff done" language, why not say it's your scripting language?

Does a shell script have to have a #! line at the start, or is this just a nice-to-have to make sure the right shell executes it?

The shebang is there so you can say:

$ ./script.sh

Instead of:

$ bash script.sh

The shebang also makes it possible for other programs to execute the script without knowing what language the program is written in. For instance, Apache/mod_cgi just needs to fork() and exec() on anything specified as a CGI. No need to check the file extention or somesuch to line it up with a specific interpreter.

It is perfectly possible to leave the shebang out. You just have know what interpreter to use.
