Crash course assuming you've just installed a distro and logged in as root. Basic knowledge required to navigate around a linux system, and learn more. I've spent only a few hours in total playing with linux, so an expert may formulate a better crash course than this... this is just my idea based on my limited knowledge and experience. 1 List files/folders a page at a time (etc) 2 Recognise difference between a folder, a file, and an executable file. 3 Description of folders in linux (var, usr, etc, bin) 4 Search/exit man pages, find the right man page if 'man x' does not work. 5 Edit text files, create 6 See running processes/services, kill them, restart them 7 See startup programs, add/remove. 8 See installed programs, uninstall. 9 Recognizing which programs need to be compiled vs already compiled, compiling (maybe) 10 Brief explanation of how you can know if a program will run on your distro 11 Update install packages 12 Installing programs with RPM or apt-get (deb format) 13 List network interfaces, list IPs, Set IP/DHCP(renew) 14 Join wireless network with no enc/wep/wpa 15 Initiate PPPoE connection 16 Deflating tar gz stuff 17 List open ports, programs listening on them, and connected sockets 18 Setup SSH to get help from a friend, log what he does. (possible?) 19 Mount/unmount usb flash drive or CD/DVD. 20 Most importantly: How to learn how to do stuff. Best places to look for different types of help.
