I use Linux for some years know.
Most questions I get are 95% the same.
This is an open-end collection of my knowledge in simple language.
Notes and personal thoughts
- Linux is the kernel, the inner core
- some drivers (for graphic cards, wifi etc.) are inside the kernel
- desktop environments (Gnome, KDE etc.) make the experience more convenient and pretty (how windows look, status bar etc.)
- additional software makes life easier
- kernel (Linux) + desktop environment + additonal software = Linux distribution (Ubuntu, Mint etc.)
- Linux is written in C, so it is fast, but a lot of bugs stem from the fact that it is not memory-safe
- I don't use a desktop environment, just a window manager (i3), no status bar etc.
- I use many small tools, e.g. vim as editor, ranger as file manager
- less packages/tools => less complexity => easier life (I have ~500 packages installed)
- learn the fundamentals first (folder structure, commandline etc.), then choose your distro
- better learn
- if you need help, read the Arch Wiki (general knowledge about Linux)
Tips and tricks
- show resolution of current display:
xrandr | grep "current"
- get current date and time:
- search for a
stringin all files in a folder
grep -R "string"
