Re^2: How to extract special charachetrs like <=, >= != from string

We can even shorten this with character class []

use strict;
use warnings;
use Data::Dumper;


while(<DATA>)
{
        print "$1\n" if($_ =~ /([><=!]+)/g)
}

__DATA__
$this vinoth $that
$this >= $that
$this gt $that
$this != $that
$this ne $that
$this == $that
$this eq $that

My question to this is, how does it know to print the `=` after the `><=!` ? Maybe i am missing a key piece of data/knowledge which would not surprise me lol.	[reply] [d/l] [select]

actually, it matches also `=>`, `<>`, `!!`, `<=>`, or in fact any combination of these four characters. It says "match these characters, one or more times". If you want only one of the 4 characters followed by a single "=", you'd write `[!<=>]=`	[reply] [d/l] [select]
