tmux

Terminal multiplexer for background processes, output capture, and session management. Every process runs in a named session you can inspect later.

Running Background Processes

Start a command in a named detached session:

tmux new-session -d -s myserver 'python -m http.server 8080'
tmux new-session -d -s build -c /path/to/project 'make build'

Keep a session alive after the command completes:

tmux new-session -d -s task 'command; exec bash'
