⚙️ Configuration

👶 Session name

By default tmux-slay will create a new TMUX session named bg (for backgroud) to run all the commands you instruct it to.

To change that you can set the env var TMUX_SLAY_SESSION:

TMUX_SLAY_SESSION="MY_SESSION_NAME"

🌅 Init window

tmux-slay keeps its session alive by creating an empty init-window named bg-init.

To change it you need to set TMUX_SLAY_INIT_WINDOW_TITLE:

TMUX_SLAY_INIT_WINDOW_TITLE="MY_INIT_WINDOW_TITLE"

🐛 Debug mode

To debug tmux-slay just set TMUX_SLAY_DEBUG to any value:

TMUX_SLAY_DEBUG=1

To debug commands started with tmux-slay the best thing to do is to enable the remain-on-exit options for the session, so that you don't loose the logs of your command:

tmux-slay debug on

To disable this again, run:

tmux-slay debug off

🧪 Examples

💻 Run an auto-reconnecting reverse SSH tunnel to the current machine

tmux-slay run -l -c -u -n ssh-forward -- \
  ssh -o ExitOnForwardFailure=yes -R 22222:localhost:22 user@myvps.example.com
