Hi Sam,

If you want the process ID of your script, then I believe you want
print "My PID = $$ \n";

print "My process id is: $$\n";

I want to print a child process ID, not a script id.

I want to print a child process ID, not a script id.

Then why didn't you say that to begin with?

my $pid = fork();
if ($pid){
#in parent
print "Child's PID: $pid\n";
} else {
#in child
exec ('child_process.pl');
}

perldoc -f fork
perldoc -f wait
perldoc perlipc

I want to print a child process ID, not a script id.

Then why on earth didn't you say so to begin with but lead us on a wild
goose chase?

perldoc -f print
perldoc -f fork (oay particular attention to the return value of fork)

Thanks for the hints. Is there other way I can print the pid of the
current process?

Thanks
