-===== Sticky Linux notes =====
-This page keeps all Linux related quick commands and shortcuts, as well as useful other information.
-==== Get OS information ====
-Get OS information from ''/etc/os-release''.
-Example: Debian:
-<code bash>
-PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
-NAME="Debian GNU/Linux"
-VERSION_ID="11"
-VERSION="11 (bullseye)"
-VERSION_CODENAME=bullseye
-ID=debian
-HOME_URL="https://www.debian.org/"
-SUPPORT_URL="https://www.debian.org/support"
-BUG_REPORT_URL="https://bugs.debian.org/"
-</code>
-Import this to a bash script via:
-The var ''ID'' is then ''debian'':
-<code bash>
-if [ -f /etc/os-release ]; then
-  . /etc/os-release
-  ID=$ID
-fi
-</code>
-Or use ''neofetch'':
-<code bash>neofetch</code>
-//installed via: ''apt install neofetch''//

-------
-==== View CPU information ====
-To view information about the CPU use
-<code bash>cat /proc/cpuinfo</code>
-------
-==== 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.
------
-==== Allow users to write to specific directory ====
-To allow any user to read/write a directory adjust permissions with:
-<code bash>chmod -R 0777 /path/to/dir</code>
-''-R'' sets the permissions recursively.
