When you run Linux on your work machine (desktop, laptop, etc), you usually want to be informed in some way about system updates being available. This post showcases two scripts for Arch Linux and Debian/Ubuntu to represent the update status in short, concise, and human understandable string, which can be included in any status bar, like i3blocks or i3status with the i3/i3-gaps window manager.
