From the last lab. Answer in your head, then open to check.
-d?new-session fails (duplicate session) but new-window adds extra windows to the existing one.Write a real workspace script, the kind you'd keep for every project.
~/project/logs/app.log is a live log, written to every second.
Write ~/project/morning.sh. It builds a session called morning with:
code, split into three paneslogs that follows logs/app.log with tail -fand finishes attached to morning, looking at code.
Run it with bash morning.sh, detach, and run it again.
morning ends up with exactly two windows, code and logs.[morning] 0:code* 1:logs
#!/bin/bash
if ! tmux has-session -t morning 2>/dev/null; then
tmux new-session -d -s morning -n code
tmux split-window -h -t morning:code
tmux split-window -v -t morning:code
tmux new-window -t morning -n logs 'tail -f logs/app.log'
tmux select-window -t morning:code
fi
tmux attach -t morning
has-session succeeds when morning already exists, so a second run skips the build and only attaches.
Challenge complete. Compare your approach with the solution: there is usually more than one good way.
