I really want to get to know more distros, and I've been thinking a bit about how to go about this.
I found a retired Lenovo ThinkPad X1 Nano Gen 1 that I've had lying unused.
The idea I've had is that I'll now use this as my main computer, and switch distros every 3 months.
Sometimes you have database tables with columns that have no values.
And you might want to hide these columns for users, but to check every row of every column in every table is time consuming. This script should help you.
