===== 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:
<code bash>dd if=/path/to/device of=image.img</code>

The ''/path/to/device'' can be found out with:
<code bash>lsblk</code>
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:
<code bash>sudo service sddm stop</code>

-----

==== 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:
<code bash>nmcli device wifi show-password</code>

-----

==== Setlocale failed Debian/Ubuntu ====
If you got any error of the following when running ''apt'' or anything else:

''locale: Cannot set LC_ALL to default locale: No such file or directory''

''perl: warning: Falling back to the standard locale ("C")''

''perl: warning: Setting locale failed.''

Just run the following command and select the correct locale:
<code bash>sudo dpkg-reconfigure locales</code>
