Hi,

as a (contrieved) example that catches SIGINT consider this: 

$SIG{INT} = sub { print STDERR "*"; };

while(1) {
  sleep(1);
  print  STDERR ".";
}

When I run this in bash and press Control-C to generate a signal I get the star printed, but I also get a "^C" in the output and I don't understand where this is coming from.

So the output looks like 

.....^C*...^C*....^C*..

Where do these "^C"s come from? Is this the shell, the terminal or what? And is there a way to supress that from within a perl-script?

Many thanks!
