batch set passwords

exodist · 07-09-2007, 09:34 PM

I have a file formatted as username,password I need to set each users password to the one in the file, I have tried:
<code>
usermod -p 'password' username
</code>
This exits fine, but the new password does not work.
<code>
echo "password
password" | passwd username
</code>

I can parse the file fine and use it in a command line, I just need a command that lets me set the password in a non-interactive way.

Create a small TCL/Expect script to set the password, and call it setpw:

Code:

#!/usr/bin/expect -f     
spawn passwd [lindex $argv 0]
set password [lindex $argv 1]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof

You can then run 'setpw userid password' from the command line or a script as root.

Does your shadow package include the newusers command? If so, it should do what you need. From the man page:

Code:

NAME
       newusers - update and create new users in batch

SYNOPSIS
       newusers [new_users]

DESCRIPTION
       newusers reads a file of user name and cleartext password pairs and uses this information to
       update a group of existing users or to create new users.  Each line is in the same format as
       the standard password file (see passwd(5)) with the following exceptions.

It's better to have a try with 'chpasswd'

# rpm -qf /usr/sbin/chpasswd
pwdutils-3.0.7.1-17.10
# echo edencc:IsThisYouPd|chpasswd
