Bash shell tricks

Shortcuts

• ctrl-r (Reverse search in command history. Tab to complete command.)
• tab (Tries to complete what ever you have typed in.)
•  !$ - last word of previous command. Handy for doing something with a file you just did something with
•  !! - entire last command. Handy if you forget to sudo something, sudo !! will be faster then editing the old command

For Loops

for i in * ; do echo $i ; bzip2 $i ; done
