Test all fonts in Figlet
October 2022
On Mac, using Homebrew
Install figlet
brew install figlet
Install lolcat because why not?
brew install lolcat
Find out your font directory using brew list figlet, then based on the installed version (mine was 2.2.5) do:
for file in /opt/homebrew/Cellar/figlet/2.2.5/share/figlet/fonts/*.flf;\
do echo "\n\n$file"; figlet -c -w 150 -f "$file" Hello World |\
lolcat; done
