does perl have any mechanism to handle exceptions? I mean if my script receive
a "kill" siginal, can I have it run some exception handling codes before exit?
thanks.

use POSIX;
then use something like sigaction to install a signal handler

yes. you can override the default signal action by supplying your own sub
routine. the name of the signals are defined in signal.h.
change %SIG, set the value corresponding to the signal you want to catch to
the name of your won sub-routine.

receive
exit?
