Useful bash commands
History: Ctrl + r
Find: find /home/user -name abc.txt
Pipeline: vi `find /home/user -name abc.txt`
Ctrl-x, Ctrl-e will bring up an $EDITOR containing whatever is currently entered into the prompt. (opposed to editing last command actually entered)
Managing remote systems and trying to figure out what hardware you're on and whether it's healthy or not: dmidecode
Repeat last command with "sudo" prepended: sudo !!
Execute <command> with the argument to your previous command: <command> !$ / !* for get all args.
