Open browser based off of certain rules (like choosy for macOS)

choosy

#!/bin/bash

URL=$1
DOMAIN=$(echo "$URL" | awk -F[/:] '{print $4}')

## Domain starts with
if [[ $DOMAIN =~ $(echo ^\($(paste -sd'|' /home/your-user/.config/url-start.txt)\)$) ]]; then
    chromium-browser "$URL" & disown
elif [[ $DOMAIN =~ $(echo ^\($(paste -sd'|' /home/your-user/.config/url-is.txt)\)$) ]]; then
    firefox "$URL" & disown
else
    firefox "$URL" & disown
fi

I made sure to follow the instructions but no entry would show up in the default apps menu of Gnome. What worked for me was to execute xdg-mime default choosy.desktop x-scheme-handler/http && xdg-mime default choosy.desktop x-scheme-handler/https in the terminal to set it manually.

Glad you could make it work. Thanks for sharing!
