Hi,
Thank you - it worked. I got my output as expected. But why is '\n'
considered so bad in perl unlike shell scripting. Why did I not get the
output with '\n'. Just curious!!!

I think Brett McCoy was correct with the trailing newline.
try this:
chomp($item = $_);
just after the foreach (@prv_lst)
in place of the line there.
You might have to chomp again for the second list.
Your array looks like it might have the following in it.
@prv_lst = ("N001\n", "N015\n");
let us know how it goes.

Hi,
I am sorry, I meant to say grep does not work inside a for loop.
regards,

Can somebody help me on what is wrong in the following piece of code?
foreach (@prv_lst)
{
$item = $_;
@list_prv = grep (/$item/, @txn_log);
print "The foll. are the Txn details for Trading Partner $item \n";
print @list_prv;
for (@txn_lst)
{
$aprf = $_;
$cnt = 0;
@list_prv_txn = grep (/$aprf/, @list_prv);
for (@list_prv_txn)
{$cnt++};
print "The number of ${aprf}'s are ${cnt} \n" ;
}
}
I dont see any values in the @list_prv eventhough I get one assiging a
value to $item
like
$item = "abc";

Thanks in advance,
Satya
