    processes & signals

    i have a parent and 2 children. One of the children has a variable which the parent retrieves through a pipe. I want to set a signal handler so that when i press ctrl + C ( SIGINT) some stats ( including the variable from the child ) are printed at the stdout.
    If the question is clear, can anyone tell me how will the processes communicate when i'll press ctrl+C so that i can, then, print?

    Using the trap command, you can do what you want.

    Rather then kill the program, you can make it do whatever you want.

    Let us know if this helps.
