I recently went through a painless transition from years of bash to fish shell in one evening. My bash setup has been stale for quite some time. I am mainly working in a bash terminal on a Mac and various Linux distributions. Bash, for me, has always been a bit of a mess to sort out the quirks of writing up scripts, loading in profile and configuration, and customizing the shell prompt. I had always put up with the quirks up until the other day when I decided to take the dive into Fish Shell.
