Is it possible to set a password from within a shell script. I can't seem to find any way to pass the new password to the passwd command. It still will always ask for New Password:.

If your script can be executed by the root or be setuided, you can simply correct master.passwd file without using passwd command. There is an 'adduser' script under FreeBSD that doing many such a things.

The script will be run as root. It's running under Sequent Dynix/Ptx 4.4.2. If you can tell me where I can get hold of the script you mention I'll evaluate it. My other alternative is to pass in the encrypted password as a string using the passmgmt command.

UNIX does not allow to pass the password as argument or read it from a file (input redirect) 'cause of security reason.
To do such things you need expect.

Sorry I wasn't reading them correctly. I'm new to this site so wasn't paying enough attention.
