trap is used to catch signals. Usually trap is used to just ignore them
(like to prevent users from hitting ctrl-c at a critical time), but it
can also be used to run a command when it gets a signal (like allowing a
user to break out with ctrl-c but make sure the script cleans up after
itself).
Refer to the man page on bash, it should cover trap in some detail.
