===== Quickfixes =====
==== Create .img on Linux CLI ====
It's quite simple to create an image of a disk, for example an SD card, therefore use the following command:
dd if=/path/to/device of=image.img
The ''/path/to/device'' can be found out with:
lsblk
For example it can be ''/dev/sda''.
Remind that using this method will include also empty parts. An image of a 32 GB SD card will later have a size of 32 GB although for example 16 GB are unused.

==== Relaunch KDE Plasma after freeze ====
Sometimes after some weeks of uptime when I entered my office in the morning, I discovered a freezed Plasma.
To fix this, enter the system via SSH and then execute this command:
sudo service sddm stop
And without re-login:
kquitapp5 plasmashell && kstart5 plasmashell

==== Show WiFi password via CLI ====
Thereby that a system is required to save WiFi passwords in clear, it can also show those passwords to you.
By running the following command, the SSID, password and a QR-code of the current connected WiFi will be displayed in your CLI:
nmcli device wifi show-password
