sorry for the mail Attila, something weird happened (I pressed ctrl+Enter
prematurely)
Fish 2.0 has the 'test' builtin:
https://github.com/fish-shell/fish-shell/blob/master/doc_src/test.txt
This provides a posix-like test interface.
Btw, it looks like the hosted fish-shell docs aren't up-to-date
Thanks
Steve
