I have a Perl script that forks.
Each fork runs an external program, parses the output, and converts the output to a Storable file.
The Storable files are then read in by the parent and the total data from each of the children are analyzed before proceeding onto a repeat of the previous fork or else the parent stops.
What exactly happens when I issue a ^C while some of the children are still running the external program? The parent perl script was called in the foreground and, I presume, remained in the foreground despite the forking.
Is the SIGINT passed to all children, that is, the parent, the parent's children, and the external program called by the children??
