unless im missing something

there is no --stidn option thats why its spitting that back at you

and if you even try -stidn it still wont work because -t isnt a valid option

no if you just use -Sidn all those are valid options for passwd

dont know what the output will be thou

i used --stdin for standard input. The above command works for other distros such as Suse, Centos , etc.... and in UNIX.
so i was quite curious why it failed in gentoo.....

any special case with gentoo...?????

Anyways thank you for your reply.

man chpasswd

Why would you do that as root anyway? Your new root password would then be sitting on the process table for some length of time, while this might not be a problem, any other user/process can then find your password.

/usr/sbin/usermod (gentoo?) is another option for what you're after... using it, is an exercise left to the reader.

What do you mean by "UNIX" when you say it works in UNIX?
