Incorrect failure return code when calling "byobu-tmux att"

[HappyCamper]

When I call "tmux att" and there are no existing sessions I get a message saying there are no sessions and the return code of 1.

However when I call "byobu-tmux att" with no existing sessions, it tries to connect and I get a return code of 0.

My full command is:

  byobu-tmux att || byobu-tmux new

...which should either reconnect to an existing session, or start a new one. The second byobu-tmux call is never triggered though because "byobu-tmux att" returns an OK code even when there was no session to attach to.

Thanks =)

I worked around this issue by using "list-sessions" to work out if there are any open sessions, then calling the appropriate command:

---------
#!/bin/bash

byobu-tmux list-sessions
if [ "$?" -eq 0 ]; then
  tmuxCmd='att'
else
  tmuxCmd='new'
fi
byobu-tmux $tmuxCmd
---------
