script to change password and email new password

You need to use expect script to set change the user password, see my script in:
http:Q_20476614.html

You need to download expect and install it on your system, and then use "autoexpect" to create a
a setpasswd script, (I can help you to modify it). this is the key part of the  job.

In your main script:
1) To generete a random password, you need to set a rule by your self, eg, create a text file or
a very login string, and then randomly pickup a string or create a password for the user.

2) run the expect script to set the password

3) mail the password to user. (use mailx, mutt etc very easy).

To be honest this would be too much trouble (I will take a closer look however when I get a chance, I didn't completely understand what your script did). Thanks though. Take a look at what I built last night. Baybe you can offer some suggestions : )
It's not finished yet. I have not decided if it will be a cron job that automatically genereates say 20 ftp accounts a day for usage and email the username and passwords out to the users or if its user interactive and I get procmail involved in executing this script when someone sends a email with a certian header everytime they need a new ftp account. I could also build this into html then the user would enter in thier email address and exicute the script. The ftp account info would then get emailed to them.
