Do it! You will never look back.

The most common tripping points are the minor adjustments in syntax, probably the biggest one being command substitution:

Bash:

    $ echo “$(ls -al)”

Fish:

    $ echo (ls -al)

You get used to it though.

Another thing many bash-ers sometimes miss is the !! substitution, e.g.

    $ apt update
    # permission denied
    $ sudo !!

This doesn’t work in fish, BUT fish does offer a handy keybinding out of the box to prepend ‘sudo’ to your current command line (submitted by yours truly). So when using fish, you’d handle the above scenario like this:

    $ apt update
    # permission denied
    # press Up or Ctrl-P followed by Alt-s
    $ sudo apt update

There are so many other great things I love about fish, but this comment is already long enough.

Be sure to read (or at least scan) through the user guide on their website. It’s an easy read and not dense. You can also view it at any time by running `help` from inside fish.

I can’t recommend fish highly enough, I’m excited for your journey :)
