Non-standard shebang formatting

[jirutka]

I found the following shebang formatting in lesson 04:

#! /bin/bash

The problem is the space between #! and the command. I know that it’s a valid shebang, technically, but it’s very uncommon and students should not be taught to write it like that.

Hm, is there a relevant standard? This is how I learned to write shebangs, and I find it a bit more readable.

Although I have always written it without a space I could not find any relevant reason to prefer one way over another. I say show students both and let them decide.

Sry, I forgot to answer. I don’t know about any relevant standard. However, I’m very active in FOSS world and maintain hundreds of packages in Alpine Linux, so I’ve seen really a lot of scripts with shebangs in my life. I can tell you that shebang with a space is extremely rare (like one in a thousand rare).

Sure, you can show students both, but you must/should choose one or another in your examples.
