Hi, I have a TCL and PERL script, which i need to start the PERL script from TCL script and i need to stop the perl script whenever TCL script sends a interrupt signal to PERL script.

I am new to PERL script, Can anyone help me to know how to trap a signal in perl and how to send a signal from TCL script to PERL script. Thanks in Advance.

Once you've started your Perl script from Tcl, all you need to do is send it any one of several signals -- including, but not limited to SIGBREAK SIGINT SIGQUIT SIGTERM -- that will cause it to die immediately. So, now all you need to know is how to send signals from Tcl -- which is a question for a Tcl forum not a Perl forum. (Unless the author of the Perl script has decided to trap that signal.) With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]
