brew on linux not working

[rubo77]

I use homebrew on Ubuntu 20.04 and when I call this it seems to install everything, but there is no resulting avifenc file:

$ brew install joedrago/repo/avifenc

Could it be, that I need zsh to be installed before calling the brew command?

[rubo77]

please add to your instructions on https://joedrago.github.io/colorist/ that you need zsh to be installed first

I didn't realize Homebrew worked on Linux. We could always just change the script to use $SHELL or something.
