@l0b0, I thought that might be impossible with unmodified Bash, but wasn't sufficiently certain I could prove it, given ways to sneak functions in through the environment for example. Of course, if it matters enough to someone, it wouldn't be too hard to modify a shell to accept $ as a function identifier. I still wouldn't recommend it!

I tried to give useful feedback that could improve other shell scripts, even though this one is doomed (or at least severely limited). | |

It looks like you can do alias "$"="" in zsh (tested, I was using the gnome shell at the time of writing)

You can't create a Bash function or alias with the name $.

Avoid eval!
