Configuration options
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
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 [email protected]
