On my server I have 100 users. (I'm superuser)
All the users have the same password: 'abcde'.
Now, I want to change (simultaneously) their password with 'newpass'.
What I should do ? Any suggestion about a script ?
Thank you in advance.

Ummm.. why in the world would you have all users with the same password? You might as well just create one account with a password for them to share for easier maintenance.

The default passwords are md5 in /etc/shadow. Change the password for the first user, grab the encrypted password from /etc/shadow, then write a script to change the remaining within the shadow file. I'd advise to just allow the users to create their own passwords though. And you should really use better passwords rather than just newpass, something with Alpha-Numeric/Upper-Lower/Special-Character combination and longer than 6 characters.

OK, I understand.
Do you suggest me a simple script to change the remaining passwords within the shadow file ?
Thank you.
