I am writing an SSH command alias to connect to my server dev-box. When I connect, I want to automatically attach to an existing session named 'work', or create 'work' if it doesn't exist yet, allocating a pseudo-terminal so interactive shell works properly. What SSH command string should I use?
| Checked | Without skill | With skill |
|---|---|---|
| The command uses ssh with the -t flag to allocate a pseudo-tty. | Passed | Passed |
| The remote command string combines tmux attach -t work with fallback tmux new-session -s work using logical OR. | Missed | Passed |

tmux keeps terminal sessions alive across SSH disconnects, splits work across multiple panes, and enables fully scriptable terminal automation. This skill covers session management, window/pane layout, keybinding patterns, and using tmux non-interactively from shell scripts — essential for remote servers, long-running jobs, and automated workflows.
tmux commands from bash scripts without user interactiontmux has three hierarchy levels: sessions (top level, survives disconnects), windows (tabs within a session), and panes (splits within a window). Everything is controllable from outside via tmux <command> or from inside via the prefix key (Ctrl-b by default).
# Create a new named session
tmux new-session -s work
# Create detached (background) session
tmux new-session -d -s work
# Create detached session and start a command
tmux new-session -d -s build -x 220 -y 50 "make all"
# Attach to a session
tmux attach -t work
tmux attach # attaches to most recent session
# List all sessions
tmux list-sessions
tmux ls
# Detach from inside tmux
# Prefix + d (Ctrl-b d)
