Allow user to specify superuser passphrase from STDIN

[g33kex]

As pass-tomb needs to be run as root, it's almost impossible to automate pass open in a workflow, for instance to ask the root password with gksudo, because there is no way to pass it to pass-tomb which waits from root password from standard input.

There should be an option to send the root password as standard input to pass open

A workaround would be to directly run echo $password | sudo -S pass open but this can't work as the gnupg password prompt can't appear on the screen if it's run as root.

Hi, it could be implemented. I will do it soon.
