`run_shell_command`

run_shell_command( command: string, max_lines?: integer, pane_id: string, suppress_history?: boolean, timeout?: number, )

tool [source]¶

Run a shell command in a pane with your user’s permissions. Runs one command you author in a pane that is not synchronized with others, rechecks the pane just before sending, and waits for it to finish, reporting its exit status. A tmux command run here acts on the session’s current window unless you target it, so pass -t "$TMUX_PANE" to mean this pane.
