Hi,
I'm not sure if I understand the passwd command properly.
What is the purpose of the $1 in the above script?
I have run this script but every server I login to, the passwd command
gets run, and I'm prompted to issue the new password, and then re-type it.
I pretty sure I'm lost on what supposed to be happening.
I would appreciate some guidence.  :)

Thanks!
Mike
