I have written about this topic before from a security perspective in the node - Think beyond Taint and warnings

 

perl -le 'print+unpack("N",pack("B32","00000000000000000000001000010110"))'

    Actually, I was trying to execute the unix command lpstat -o and passing in the variable $name. Which is the result of another command and whose value I don't know. Thanks for input --kirk123
