Hello Monks I have a file that I want to modify which conatains the follwing : 
#MYFILE
if [ $me = you ]
then 
export ORA1=one
export ORA2=3f34
export ORA3=zzzz
fi

[download]
what I want to do is change the value of ORA3 to become 0; I am now copying to file and trying to modify it and rename it . Don't seem to do the right thing. 
open MYFILE, "<$myfile";
 open COPYFILE, ">$copyfile";
  while(<MYFILE>){
if (m/(ORA3=)(\w+)/) { $value=$2 }
$value =~ s/$value/0/;
  print COPYFILE $_;
   }
   close MYFILE;
  close COPYFILE;

system (" mv COPYFILE MYFILE ");

Can someone help in finding the problem or advice on a better way. thanks
