Make shellcheck happy

I don't use shellcheck and this isn't intended as some kind of golden shellscript you can just use as-is. You're expected to understand and modify it as needed. Given that, and that none of the changes here seem to fix actual bugs or significantly improve style, I don't see the point in making it conform to an arbitrary linter's standard.

an arbitrary linter

What linter would you suggest for all of my shell scripts?

[marcan]

Whichever one you like, I just don't see why a random script you found on github (especially one as trivial as this) has to make it happy :-)

Whichever one you like

I would really love to know what linter you find helpful.

The only bash linter I know is shellcheck. Up to now I use it before committing a script.

I do not personally use a linter for shellscripts.

Thanks.
