Re: [K12OSN] changing passwords for multiple users

[Petre Scheie <petre maltzen net>]

I wrote something a few years ago to do this, using expect which is part 
of tcl/tk.  Here the expect script:

#!/usr/bin/expect -f
#
# chpw.exp: Sets default password for new accounts.

set pw [lindex $argv 1]
set id [lindex $argv 0]
spawn passwd $id
match_max 100000
expect -exact "Enter choice here: "
send -- "p\r"
expect -exact "New password: "
send -- "$pw\r"
expect -exact "Re-enter new password: "
send -- "$pw\r"
expect eof

Put the above in a file, and then call it with the userid and new 
password as the parameters, and it will change the user's password. 
Then you can just do

for x in `cat id_and_pw.txt`
do
./chpw.exp $x
done

where ic_and_pw.txt is a file that contains a series of rows with each 
row having an ID and its respective new password.
