Hi Monks,

I have seen the post here about "Getting lines in a file between two patterns" (http://www.perlmonks.org/?node_id=979946)

I was curious that what if I need to extract only the second block of lines that meet the pattern?

Is there something that we can do via (/START/ .. /END) pattern matching? Many thanks

That is:

I have a text file -

abc
efg
...
START
lines not to be extracted
END

START
lines to be extracted
END

START
lines not to be extracted
END

...

I think I find a way. Thanks guys

 
my $count = 0;
 11 while (<$fh_r>) {
 12   if (/START/ .. /END/) {
 13     $count++ if /START/;
 14     print if ($count == 2);
 15   }
 16 }
