waybar-apt-updates

A simple Waybar update checking script for distros using the APT package manager. It is a general script and could work with other bars or just be run in the terminal.

Credit goes to this post for the update command.

How to use

Download the checkupdates script, put it in your PATH and make it executable (chmod +x checkupdates).

To configure, add the following to your Waybar config (~/.config/waybar/config).

"custom/updates": {
    "exec": "$HOME/bin/checkupdates", // <--- path to script
    "on-click": "$HOME/bin/checkupdates", // refresh on click
    "interval": 900, // refresh every 15 minutes
    "return-type": "json",
    "format": "{} {icon}",
    "format-icons": {
        "has-updates": "", // icon when updates needed
        "updated": "" // icon when all packages updated
    }
},

To style use the #custom-updates ID in your Waybar styles file (~/.config/waybar/styles.css).
