@eternal44 my guess is that this is a version issue. It looks like the -A
flag was added to the new-session
command in version 1.8 (March 2013).
You can check your version by running tmux -V
(note the big v). Should be 1.8 or higher to work with tat
, but I’d recommend upgrading to 1.9a or 2.0 via your package manager anyway.
