in reply to Control C in PERL?

Control-C is a special keyboard character caught by the terminal drivers. It passes the SIGINT to the foreground process. While it's easy to ignore this single character sequence as shown above, it may be better to use Curses to ensure that you ignore ALL input while your loop is running. Also, Curses can help you to "beautify" your output. Also, you could assign ^C a subroutine or some instructions to notify the user that the key is being ignored. The C docs will help you more than the perldocs, so look at man curs_inopts(3X). Good luck!

    You can also use Term::ReadKey to help control the signals. This works better on Win32 systems for some reason.

marioroy At a large firm, had to awaken a security guy a few times so that nobody would catch him sleeping.
