in reply to how to make a password dissapear?

What are you trying to do? read a password? right, read password, I mean ReadPassword, or better yet ReadPassword ;D

Term::ReadPassword is kinda cool, but do remember to read the pod, and heed the warnings of the author.

Disclaimer: Don't blame. It came from inside the void

perl -e "$q=$_;map({chr unpack qq;H*;,$_}split(q;;,q*H*));print;$q/$q;"
