Question communicating wth another user aside from "wall" and "write"
Hi,

Can anyone suggest a Unix command or c-shell algorithm to simulate to behavior of "wall" command minus the "all users"? What I'm trying to do is to send a notice to just one particular user but i dont want other remotely-logged-on users to receive the message (on the pseudo-terminals). I cannot use the "write" command for three reasons:
1. I (sender) will not be typing the message from standard input (instead, i will be using a file
input)
2. I (sender) is not logged in to the same host as the receiver (but the receiver's host is known)
3. I want the message to appear on all terminals of the intended receiver.

Thanks in advance for your ideas...

SYSTEMD-ASK-PASSWORD-CONSOLE.SERVICE(8) 	       systemd-ask-password-console.service		   SYSTEMD-ASK-PASSWORD-CONSOLE.SERVICE(8)

NAME

       systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path
       - Query the user for system passwords on the console and via wall

SYNOPSIS

       systemd-ask-password-console.service

       systemd-ask-password-console.path

       systemd-ask-password-wall.service

       systemd-ask-password-wall.path

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.

       systemd(1), systemd-tty-ask-password-agent(1), wall(1)
