tmux Session Control

Control tmux sessions by sending keystrokes and reading output. Essential for managing Claude Code sessions.

When to Use

• Monitoring Claude/Codex sessions in tmux
• Sending input to interactive terminal applications
• Scraping output from long-running processes
• Navigating tmux panes/windows programmatically

For one-off commands, non-interactive scripts, or starting new processes, use exec directly.
