Operating Systems Linux Set password in single command

What Linux system are you running?
The man pages for both SUSE and UBUNTU indicate that chpasswd update passwords in batch mode, so it is not interactive. It does not require any flag to be non-interactive.

chpasswd works fine noninteractively as root. It just reads the user:pass pairs from stdin. For example, to change xyzzy's password:
Code:
echo "xyzzy:qwertyuiop" | chpasswd

Anyone but root needs to authorize themselves with PAM somehow, usually by password. This is as it should be I think. Obviously a powerful bulk password changing tool shouldn't be available to just anyone...

This may vary on your system if your PAM settings are different.
