Is there any way to echo something to another terminal session, obtained from the who command? For example, root user echoes a message to a different user's terminal session, after getting their session from who. Is this possible?

  • Something like `write someone pts/2` after `mesg y`? Or directly `echo "Hi" 1> /dev/pts/1` – Pablo Bianchi Nov 04 '22 at 01:54

That's very much possible with the write command

Example

$ write username </dev/ttyX>
