When you execute a command in your shell and it returns an error because 
you make a typo, you run this command and it looks at your history to 
find your last command, runs a bunch of rules to figure out what you 
meant, and submits the corrected line.  You can specify a parameter to 
run the fixed command without confirmation if you know it will do the 
right thing.  You can also make up your own rules for it.
