MySQL Foolproof solution to determine if your script was invoked by cron :)

Nevermind... Smilie
I found out the solution

#!/usr/bin/perl
#Find my parent pid
#CR=`ps -ef | grep -i cron`
$parentpid=`ps -ef | grep "(/remote/idshome/pooja/parentpid.pl 1>/remote/idshome/pooja/OUT 2>/remote/idshome/pooja/ERR)"|awk '{if(NR==1) print \$3;}'`;
@cronpids=`ps -ef | grep -i cron |awk '{print \$2;}'`;
print "My parent pid is\n$parentpid\n";
print "Cron pid is\n@cronpids";
foreach $pid (@cronpids){
if(chomp($pid) eq chomp($parentpid)){
print "I was invoked by cron\n" ;
last;
}
}
