• tab completion works in more places than you might expect
• ctrl-a/ctrl-e for start/end of line
• ctrl-u to clear the command you’ve typed so far but store it into a temporary pastebuffer
• ctrl-y to paste the ctrl-u’d command
• ctrl-w to delete by word (I prefer binding to alt-backspace though)
• ctrl-r to search your command history
• alt-b/alt-f to move cursor back/forwards by word
• !! is shorthand for the previous run command; handy for sudo !!
• !$ is the last argument of the previous command; useful more often than you’d think
• which foo tells you where the foo program is located
• ls -la
• cd without any args takes you to your home dir
• cd - takes you to your previous dir
• ~ is a shorthand for your home dir
