Re: Can we use variable for pattern match and extraction

You are almost correct with the syntax; if you want to match a string against a regex, you will want to use

ABC: while ()
{
   #print "entered into while loop\n";
   if ($_ =~ /$net_extract/) 
   {
      $count = 1;
      print "hello\n";
   }

And the other thing that might be what you want is: `ABC: while () { #print "entered into while loop\n"; if ($_ eq $net_extract) { $count = 1; print "hello\n"; }` [download] These are 2 quite different approaches though, kvale's will execute the loop if any part of `$_` matches `$net_extract`, whereas the in the code above the loop will only execute if `$_` and `$net_extract` match exactly.
