Control tmux sessions and capture output

Control tmux panes and sessions for interactive CLI automation

Controlling long-running interactive CLI sessions (CI/CD pipelines, SSH tunnels, Postgres shells) from scripts without direct terminal access.

• · Session:window.pane target
• · Text to send, special keys (C-c, C-d, Escape)

• · Pane output capture (last N lines or full scrollback)
• · Command execution status

• · tmux

• · tmux session already created and running
• · Caller has shell access to tmux binary

• · Invalid session:window.pane target causes command failure
• · Session closed or pane killed before command execution
• · Paste/newline handling requires -l -- flags to avoid surprises

• · Supports capture-pane with -S - for full scrollback
• · Helpers: find-sessions.sh, wait-for-text.sh for prompt detection
• · Tested pattern for permission/confirmation prompts
