Let's say you're typing a command, and you do a typo. The shell will offer you a correction ... for example, you type:
pingeand it'll ask you:

unset autocorrectYou can put those in whatever appropriate .tcshrc file or such-like place you keep such things. BTW, use at your own caution ... I'm a total Unix newbie who swiped this off a Google search result, and I take NO responsibility for absolutely anything in the whole wide world. ;-)
unset correct
