script to change password for all users
We have a server where we have a number of user ids and we also have the list of old passwords in a CSV file.
Now we want to change the password of all the users and assign them a default password.Can we write a shell script to do that.
I am planning to read the user name and corresponding password from CSV file.But how to login to the server with the same user and change password
with passwd -r file command.
Once i type login the exported paramter values are lost.
Any suggestion or sample script will help.
thanks
Deepak

Hi there,
Does anyone know of a way I can become a different user in a script? I need to run a script as one user (not root), and change to another user half way through.
It stops and asks me for the password, and I can't find a way to feed the password in through the script.

yppasswd
yppasswd(1yp) yppasswd(1yp)
Name
yppasswd - change password in yellow pages (YP) service.
Syntax
yppasswd [ name ]
Description
The command lets you change your password in the yellow pages (YP) map, a network data base service. Only you or the superuser can change
your YP password.
When you enter the command, the program prompts you for the old password and then for the new password. Note that the passwords are not
displayed on the screen.
Next, the program asks you for the new password again, to verify that you have typed it correctly. If you do not type the passwords cor-
rectly, you will receive an error message after you enter the new password.
Your new YP password must meet one of the following requirements:
o It must be a combination of at least six alphanumeric characters, or
o It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence.
The command does not change the YP password. This command only changes the local password file and not the YP master password file. See
Chapter 3 of the Guide to the Yellow Pages Service for further information.
Diagnostics
Please use a longer password
Your new password does not meet the minimum length requirement.
Mismatch- password unchanged
You misspelled your new password or its verification.
couldn't change passwd
Your new password can not be activated. It must be different from your old password and your login name.
