Signals and the TRAP statement

• To set a trap for SIGINT:

trap 'statement; statement; …' INT

• To turn it off again:

trap INT

• To prevent any SIGINT handling (ignore signals):

trap " " INT

• Be cautious in trapping SIGINT: how will you stop a run-away script?

• To see what traps are set (you can see traps for specific events by listing the names or numbers):

trap -p

• To list the names for signals 1 to SIGRTMAX:

trap -l # that's an ell, not a one
