using-tmux-for-interactive-commands

Automate interactive CLI tools by creating detached tmux sessions, sending keystrokes with tmux send-keys, and capturing output with tmux capture-pane. This approach lets you programmatically control tools that normally require live terminal input, such as vim, git rebase -i, and Python REPLs.

Yes, tmux enables programmatic terminal control through detached sessions. Start a session with tmux new-session, send input using send-keys with special keys like Enter and Escape, and verify results by capturing the pane output—all without interactive user intervention.

Use tmux send-keys to transmit text and special keys to a detached session. This command accepts both regular characters and key names like Enter, Escape, and C-c, enabling precise control over interactive commands and workflows that require keystroke sequences.

Capture terminal screen output using tmux capture-pane with the -p flag to print the pane contents. This lets you extract and verify command results, validate interactive tool state, and automate verification logic within your workflow.

Yes, tmux must be installed and available in your environment. The skill relies on tmux as its core runtime to create detached sessions, manage terminal control, and handle input/output for interactive CLI workflows.

Tmux session control works best for deterministic, text-based CLI tools with predictable output. Tools with complex UI rendering, mouse interaction, or real-time graphical elements may not respond reliably to programmatic send-keys commands or screen capture.
