Change UNIX password by batch via a shell script

[Rita Li]

We are going to launch a new application server to replace the old one (a database application)

We held some basic trainings more than a month ago to teach all the users how to change the UNIX and/or application's password. Some did change his/her UNIX password during the training but most of them have forgotten what's the new password that they have changed to

We have 400+ user acocunts & I want to reset all the UNIX passwords then send out an email to tell every one how to logon the first day when the new application goes production

eg. The Login ID is "test", the password is "test123". (passwd = adding 123 to the login ID). Then issue a "passwd -f $username" command to force everyone changing his/her password at the first logon

How can I do this password change by batch via a shell script?

Appreciate anyone who can reder me help on this

Shalom Rita,

Essentially you need a user list.

cat /etc/passwd | awk '{ print $1 }' > list
# edit the list
while read -r uname
do
# passwd reset code goes here.

# call SEP's handy email with attachment script
done
# email attachment script:

This script is a little over-engineered and you might just want to harvest the email portion of it instead of using the whole thing.

Able to come up with a script finally that works, thanks
