CHANGEPASS

changepass − update an user’s password

changepass

changepass is a chpasswd clone, it might be useful on platforms that doesn’t have such a command like Solaris.
Most GNU/Linux distributions have chpasswd (8), on FreeBSD you can use "pw usermod name -h 0" but many commercial Un*ces doesn’t have tool like this. An alternative is to update the user’s password in script with usermod
but it’s possible to see the encrypted password in the process list, which is not very secure.
changepass reads a list of user name and password pairs from stdin and updates the users passwords
Each line has format:
username:password

-h,--help print this help

-n,--nopam don’t use pam
-p,--pam use pam (default)
-e,--encrypt password is already encrypted, this option will disable pam
-m,--md5 use md5 encryption, this option will disable pam
-v,--verbose enable verbose output

cat user_password_pairs | changepass
