aliasing fi

I think I mentioned not long ago that I found I'd been aliasing fi=finger which breaks if loops in my shell, and marveled that it took so long to find that. It makes more sense to me now.

1) Yeah, I didn't script much.
2) When I did do an ad hoc script at the prompt, it was a for loop.
3) Scripts you get are mostly bash scripts.
4) Even an explicitly written zsh script wouldn't have a problem: my aliases are loaded by .zshrc, which is loaded by interactive shells, i.e. not script shells[1].
5) Only when I tried pasting an if loop into a *function*, also loaded by .zshrc after my aliases, did a problem occur. Possibly it had occurred before and I simply gave up on some unnecessary function that mysteriously didn't work.

[1] This also sheds light on past failures to ssh in somewhere and invoke a function directly: not an interactive shell, so no functions loaded. When I try 'ssh ... "zsh -i script_invoking_function"', it works. So if I want remote function invocation, I'll need to use -i or to load functions outside of .zshrc.
