I am trying to do the follwoing in perl

Code:

nawk ' {
        if($0 ~ /^\*Main Start/){
	     while( $0 !~ /^\*Main End/){
	     print $0;
             getline;
        }
     }
 } ' my.txt

One more code I want to do it in perl pls give me some basic idea how to do it without creating any temporary files ..

Code:

TMP=/tmp/my_tmp$$
nawk '
/\*Main End/{
split(x,arr,",")
print "Loop  " arr[1]
};
{x=$0
}
' my.txt > $TMP 

nawk '{
if($0 ~ /^Loop/){
    loop = $2 
    next;
  }
if($0 ~ /^\*Main Start/){
     printf "\nrepeat ("
     print  loop

} ' $TMP $my.txt

Thanks & Regards,
