Red Hat Enterprise Linux, force password reset on next login

So you set up a new account for a user on a Red Hat Enterprise Linux system and you want to set it to someting simple and then have the user change it next time they log in.  One way to make sure that the user changes the password next time they log in is to force a password change by setting the password expiration to zero days since it was last changed.

# chage -d 0 {user-name}
# chage -d 0 user

You can also use the “usermod”  command to change other properties about the user’s account.
