  Heh, no problem here are 2 more bang tricks. !<charachters> runs the last command you ran that starts with the characters you type. !gre # will run the last command starting with gre (so probably grep) If you type history, then !<number to the left of the history command>, the shell will execute that command. $ history # shows command history $ !200 # executes command 200
