Regenerate Snap profiles (Ubuntu)

#!/bin/bash

## Get a list of all installed snaps, filtering out the system core components.
## The 'snap list' command outputs a table; awk is used to extract the snap name (first column)
## and 'tail -n +2' skips the header line.
## 'grep -v' filters out the core system snaps like core, core18, snapd, etc.

SNAP_LIST=$(snap list | tail -n +2 | awk '{print $1}' | grep -v 'core\|snapd\|gtk-common-themes\|gnome-3-38-2004\|kde-frameworks-5-99-qt-5-15-8-core20\|content')
