       chpasswd [-e]

DESCRIPTION    [Toc]    [Back]

       chpasswd  reads	a  file  of user name and password pairs from standard
       input and uses this information to update a group  of  existing	users.
       Without the -e switch, the passwords are expected to be cleartext. With
       the -e switch, the passwords are expected  to  be  in  encrypted  form.
       Each line is of the format


       The  named user must exist.  The supplied password will be encrypted as
       necessary, and the password age updated, if present.

       This command is intended to be used in a large system environment where
       many accounts are created at a single time.
