Question

My issue is related to using fork() within Perl code.
I wish to fork a new process and capture its PID and return it back to the callee program. Is there some command in Perl which would make this possible?

Answer 1

my $pid = fork();
if ($pid == 0)
{
    # We are the child.
}
elsif defined($pid)
{
    # We are the parent of child with PID=pid
}
else
{
    # The fork failed
}
