A lot of Linux people have been singing the praises of Zsh for a long time and even as a Mac user it was always an option but I never bothered. Part of that is that I mostly stay in Emacs and don’t use the shell as much as I used to and I was happy with Bash so it never seemed worth the effort to upgrade.
Then, of course, Apple made up my mind for me by making Zsh the default shell in macOS. A useful way of thinking about Zsh is as a superset of Bash so I mostly haven’t noticed any changes except for fixing the prompt string.
Over at the Twilio Blog Lizzie Siegle has a nice post on some Zsh tricks that show some of its benefits. There’s no point in me relisting those tricks but if you’re a Zsh user you should definitely take a look. In particular, if you’re on a Mac and got (more or less) force changed into Zsh, you probably haven’t explored all it has to offer so you should definitely read the post.
Siegle’s post by no means exhausts all the additional goodies you get with Zsh. You can even get Oh My Zsh, a whole package of additional plugins. The post has links to a cheat sheet and list of Zsh plugins if you want more information.
