Extract script archive...
Install scripts...
Set version to 5.7.3+337 ...
Attempt update of login bash profile on OSX...
Added sdkman init snippet to /Users/xxx/.bash_profile
Attempt update of zsh profile...
Updated existing /Users/xxx/.zshrc

It adds sdkman init snippet to bash and zsh, but I'm currently using Fish (I moved from ZSH a while ago) and it doesn't seem to support it.

I might try to create a PR with the right script for Fish shell if you agree on that. And it's a good way to start my Hacktoberfest!

If you'll forgive the plug, may I recommend sdkman-for-fish?

A draft for showing it while installing SDKMAN! is here: sdkman/sdkman-hooks/pull/9

Given that a complete rewrite in Go is underway (which will make special support for different shells obsolete, I assume), I don't think we should expect much "official" support here. I'm sure @marc0der will check out pull requests for documentation?
