Do you really want your password on the CLI in clear-text and in your history?

Code:

echo "Sup3R$3kre7" | passwd --stdin nirmit

passwd --help
man passwd

I don't know what the purpose is for your request, but I guess that it has to do with changing a lot user passwords at once. In such a case (depending on the amount of users) you might just as well create a shell script to tinker with the passwd and shadow files directly. Dangerous, but possible.

Interesting: I thought I was nuts because I had never seen that option before. I checked, and on my Debian system, there is no --stdin option. On a Mac, the option appears in the man page, but it doesn't actually work. (Every time I try it, I get an "illegal option" error.) The Mac version also helpfully offers a -noverify option, but that doesn't work either. Odd.
