Read into BASH, you may know it as the “Terminal” or “Console” people may also call it the “Shell” it’s essentially the heart of all modern Linux distribution’s and once you wrap your head around the command structure it’s pretty straight forward!
Key commands:
-
cd== Change Directory -
sudo== Root privileges -
mkdir== Make directory -
rm -f== Remove file/directory with force -
touch== Make a new file -
nano== Text/File editor -
cat== Read file contents and print to shell
Commands don’t need to be complicated! For example nano /home/SomeUser/Downloads/SomeRandom.txt will open the text editor to SomeRandom.txt in the /Downloads directory of SomeUser
Each Linux distribution will come with a package manager, Debian based distributions like Ubuntu, Linux Mint, Kali Linux have dpkg and APT as their package managers and Arch-based systems have Pacman,Fedora-based systems use DNF.
If you really can’t handle the complexity perhaps trying an immutable distro like Bazzite which is more locked down, less easy to break and geared towards folks like yourself.
