I put a simple echo command in a CLI tty by user1 expecting it to reach user2 who is logged in a separate tty.
echo "Hello, world!" >> /dev/tty5
I expected user2 to get the echo message but nothing shows up.
Does each user get his/her own "set" of tty[1-7]?
Edit: I suspect this may be a permissions issue. I was actually exploring
cron jobs and had set a
cron job to
echo a "hello world" message every minute from
user1 logged into
tty2 directed to
user2 is logged in but
user2 never got the echoed messages.
