tl;dr: I have an irssi proxy screen session running in the background. I'm running byobu -R -S byobu;exit in ~/.bash_profile to start a second session instead of reconnecting to the irssi session, but it starts a third session when I log in twice (e.g. once through the local terminal and once through SSH). How can I make the secon login reconnect to the first?
I had previously enabled byobu on login for my server. This worked fine, and I would get the same underlying screen session no matter where I logged in from.
However, then I added a second screen session to the server's boot:
[alex@alex-ubuntu-server ~]$ cat /etc/rc.local
#!/bin/sh -e
# [clipped out default ubuntu rc.local header]
# run an irssi proxy under screen as user alex
sudo -H -u alex screen -d -m -S irssi-proxy irssi
exit 0
[alex@alex-ubuntu-server ~]$
From then on, this command (which was put in my ~/.bash_profile by byobu configuration):
_byobu_sourced=1 . /usr/bin/byobu-launch -S byobu
would connect to the already existing irssi screen session, instead of creating a new session. This was obviously not ideal, so eventually I settled on the following command:
byobu -R -S byobu;exit
Then intention was to name the screen session, thus allowing a reconnect to the same name when I logged in again through e.g. SSH. However, when I login again, I get a fresh screen session instead of the existing one (as you can see in the example below, this has already happened once).
[alex@alex-ubuntu-server ~]$ screen -ls

# so these weren't really one after another, as shown here

I'd prefer not to switch to tmux. How can I construct a byobu/screen command that reconnects to the existing second screen session if possible, but otherwise starts a new (second) session?
