Thanks Ranga. It works.

What does "8" signify here?
Also Can you please explain how this works?

---------- Post updated at 03:30 AM ---------- Previous update was at 03:19 AM ----------

I have a small clarification. This doesnt work for various patterns as shown below.

Code:
 
#!/usr/bin/perl
use strict;
use warnings;

my $filename = "abc_yyymmdd_hhmiss.txt";
$filename =~s/(.*).{8}\.txt$/\1*.txt/g;
print("file name is $filename");

Code:
file name is abc_yyymmd*.txt

can you please get me clarified on that
