UNIX for Dummies Questions & Answers

Hi,

I'm trying to create a shell to change some user password with random string.

I've tried to use stdin redirection to supply the new password by a response file:

passwd theuser < respfile

but I continue to be prompted for supplying pwd via console keyboard.

Can you help me to find a way to change pwd in an unattended mode?

Thanks a lot.

Another way you could do it is to use Perl to create another password/shadow file, maniuplate the temp file and copy it over the old.

The first solution requires a big amount of work but would solve a set of cases larger than the simple password change task.

The second is more specific for my problem but is non suitable for all Unix OS (some doesn't use passwd/shadow to store passwords).

For Linux someone told me about chpasswd command that accepts a file for account/password definition.

This could solve the problem for Linux based platforms.

Thank you for help.
