Reading Pane Output

Always use capture-pane to read what is currently visible in a pane:

# Capture visible output from a specific pane (target format: session:window.pane)
tmux capture-pane -t 0:1.0 -p

# Capture with scrollback (last 100 lines)
tmux capture-pane -t 0:1.0 -p -S -100

# Capture all scrollback
tmux capture-pane -t 0:1.0 -p -S -
