Change user password via bash script

[scumboss]

Hi All

I'm trying to change a user's password via a bash script I found this solution on another forum but it doesn't work does anyone have any other solutions?

The error I get with the following is unrecognized option '--stdin'

passwd can use the --stdin flag
passwd --stdin <user> <password>
note: only root can do this, but for any user

Sorry guys sorted it. Found a solution

echo username : password | chpasswd
