FAQPage Schema

How do I keep a terminal command running after I close my session?▼

Create a detached tmux session with a long-running command. Tmux is a terminal multiplexer that maintains background processes in named sessions, letting you close your connection while tasks continue executing. Use `tmux new-session -d -s name 'command'` to start detached.

Can I send commands to a tmux session without attaching to it?▼

Yes. Tmux lets you send commands to running sessions and windows directly from the command line without attaching. Use `tmux send-keys -t session:window 'command' Enter` to inject commands and capture output from panes remotely.

How do I capture output from a background process in tmux?▼

Tmux stores pane history and lets you capture live output from running processes. Query a pane's buffer with `tmux capture-pane -t session:window -p` to retrieve command output without interrupting execution.

What's the best way to manage multiple terminal windows for development tasks?▼

Tmux coordinates multiple windows and panes within sessions, isolating related tasks. Create windows for different tools—dev servers, test suites, logs—attach when needed, and detach to keep them running independently.

Do I need separate tmux sessions for different projects or services?▼

Yes. Tmux supports per-socket isolation, allowing dedicated sessions for different projects and services. Use descriptive session names and separate sockets to prevent conflicts and keep agent work organized across concurrent operations.

Why would I use tmux instead of running commands in the foreground?▼

Tmux decouples processes from terminal lifecycle, so work survives disconnections and terminal closures. It also enables output history capture, coordinated multi-window workflows, and reliable management of dev servers and test suites that must stay live.
