I am using 'doveadm pw' from inside a bash script to generate the salted hash for a user provided password. I call it like: doveadm pw -s SHA256-CRYPT -u $user -p $password
Is there any possible way to use piping (so it won't show up in ps for example) to pass the username and password to 'doveadm pw' instead of using arguments?
% man doveadm-pw

Thanks. Reading the manual was the first thing I did before posting to the list.
I'm not sure if this is relevant for the question, but I forgot to mention that the user enters it's password through a 'dialog --passwordbox'.
I guess my question is: it possible to pipe that into 'doveadm pw' directly from memory, without using any kind of on-disk temp file?
