I ran "pkg ins fish" and installed fish. Then I ran fish. (You have to type /usr/local/bin/fish . If you type "fish", you get /usr/games/fish, which is the Go Fish game.) It says "fish:" and accepts input, but does nothing. It does not appear to exit when I type ^D or ^C, but whatever I type after ^D is eaten not by fish but by my usual shell once I kill the fish.

fish on Ubuntu Linux gives a prompt "phma@caracal /v/w/W/src>" and runs commands like any other shell.
