It nearly is! I love fish powerful completion, just find it annoying that it is triggered automatically. Also fish syntax seems saner than bourne's, and I love it (but miss process substitution from time to time). Unfortunately, I cannot stand the flashiness. With some work, I have managed to disable all colors by setting a lot of fish_color variables in my configuration file. But the auto-completion drains me after a few minutes of use. As if you are speaking to somebody and they complete all your sentences! Even if the completion is correct, isn't that extremely annoying?
