Quickly add user accounts to the system and force a password change on first login

This command is a bit Linux specific, as --stdin doesn't exist for passwd on many Unix machines. Further, useradd is high level in most distributions and Unix derivatives except for the Debian family of distros, where adduser would be more appropriate. The last bit, with chage, will force the user to change their password on new login.

What others think

the word 'chage'; is it right?

Yes- "change password aging".

Comment by atoponce 280 weeks ago

'-e' can be passed directly to 'passwd'. This immediately expires the password making 'chage' redundant in this example.

@rjc This is only true for passwd coming from the GNU passwd package, and as such not 100% portable. For example on HP-UX 11.11 and Solaris 10, 'passwd -e' is used to modify the login shell.
