Perl newbie here. Can someone please help me with this? I want to write a perl script to count the number of digits, characters, whitespace characters and words in a string. I feel lost. I've tried writing a while loop to do this, but I end up with an infinite loop. 
while($input =~ m/(\w+)/g)
{    
    if( $input =~ m/[\w\s]/g)
    {
        $count++;
    } 

}
