Execute commands in a user-visible tmux pane to enable collaborative terminal operations.
Determine the target pane
The target pane is specified by the user or obtained through discovery:
tmux list-sessions -F "#S"
# PANE Title
tmux list-panes -a -F "#S:#I.#P #T"
# PANE Title CMD PWD
tmux list-panes -t main -F "#S:#I.#P #T #{pane_current_command} @ #{pane_current_path}"
The examples below use $PANE to represent the target pane (e.g., main:1.1）。

Tip
- For long-running tasks, just confirm they have started; no need to wait for completion
- When the output is too long, increase the number of
-Slines (e.g.,-S -200） - Determine command completion: capture multiple times to check whether the shell prompt appears
