Full Discussion: Bash scripting mask password from ps

I don't think ps would see anything more than the variable name, but I could be wrong. Its hard to tell without seeing the whole code.

I don't know how much more coding you wish to do with the script, but one option might be to use gpg to encrypt a file with the password or passwords in it. Then you could just use the password to decrypt the file in the script and pass the real password or passwords to a variable in that script when decrypted.

Ansible may be a good tool for that as well. Again, hard to say without looking at the code.

DESCRIPTION

       systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
       SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
       boot.  systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
       intended to be used after boot to ensure that users are properly notified.

       See the developer documentation[1] for more information about the system password logic.

       Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line
       parameters.
