I'm working on a phone so I can't try it now. But a trick I have seen on codegolf.stackexchaneg.com is to

• Name the file ˋhello worldˋ
• Make the shebang something like ˋ#/usr/bin/echoˋ
• Copy any algorithm into the file (won't be executed)

I think that some variation of that should print the filename instead of running the file. But I can't test it right now.
