Hi Monks. How does one test whether a daemon is up and running ?? My code follows :

my $rc_testd = grep /testd/ , ( `ps -ef` ) ;
if ($rc_testd > 0)
    { 
    print "testd daemon is up and running \n" ;
    exit 1 ;
    }

The snippet is in a script called " testd.pl" . The problem is that this code finds itself running and always exits. What I really want to do is to see if a previous invocation is still active ?? Any advice will me much appreciated. TIA
