Gnome Terminal and fish I have been using the default Gnome Terminal with the fish shell for a long time and it has served me well. Since fish provides a lot of functionality out of the box (including meta information about git repos in the prompt), I have stuck with it for the convenience. However, there is ONE major downside to fish; it is not POSIX compliant.
Why ditch fish? See what had happened was… Non-POSIX compliant wasn’t a big problem until I found myself writing a couple helper functions with fish syntax.
