I'm trying to set "fzf - Fuzzy finder for your shell <http://goo.gl/PeZ82X>" for the fish shell <http://goo.gl/Gf4S1p>. The problem is that interactive commands don't work when I use it in command substitution. Example:
This command works: (echoes all the files in the current dir, and I can interactively select one by fuzzy-finder) ls | fzf But this one doesn't work: echo (ls | fzf) It just immediately returns empty string. It doesn't work for any interactive command, so if you haven't fzf, you can test it with, say, off the top of my head, chsh: This command works: (asks for password) chsh but this one doesn't: (immediately returns empty string) echo (chsh) More, when I try to exit fish, it says that "there are stopped jobs", i.e. the command starts and immediately stops. How to make it work?
