Bash script to reset admin password with chntpw
 

I'm trying to write a script that will automatically reset or blank a windows admin password.

The idea is to use chntpw point it at a SAM file and run
chntpw -l SAM
to list users, grep the admin or Administrator account and automaticly append an "*" to reset the password.

However, I dont think its possible to redirect an input into chntpw as
the command requires several y and n input responses, not just a single input.

Is there any way to pass multiple inputs into the chntpw command? Thanks in advance.

Best chance would be an "expect" script AFAIK. Searching LQ for "expect script" should turn up some threads.


That's a nasty tool. Please make sure you build in some safeguard so it doesn't get used in anger easily :-]

Thank you, I found the expect home page, and good point, in the wrong hands it could be dangerous, so I'll include some sort of password or other security measure.
