Bash scripting mask password from ps
Hi All,


I have a script, which prompts me for my password input, then it passes that password onto an argument for another script which is then passed onto an expect script which automates my logins to a bunch of servers to execute my commands.

example.

script A - request for password, pass password variable to expect script command
expect command - ./expect $password ssh@server “command”
expect script - obtain password from $argv 0 and execute.


I've seen a few posts about this request and can't find anything that works. Is anyone able to guide me in the right direction? I have tried using file descriptor and no luck.

Also, no ssh keys is not an option and hard coding passwords in files.

Thanks

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.
