New zsher here. When I do $ ssh [email protected] all is well. But when I create an alias in .zshrc: alias foo='ssh [email protected]' and run foo, I get "Could not resolve hostname". Question: how do I begin to figure out what's going on? It all works for me in bash, but that has nothing to do with me knowing what I'm doing! Update: When I change my alias to alias foo='user@ip_addess_for_foo' it works. A bug, maybe.
