Nếu bạn đang ở trong vỏ hộp bận rộn (tro), bạn không cần phải lo lắng về bí danh vì chúng sẽ được chạy dưới dạng các lệnh theo mặc định IIRC. Dù sao busybox --helpđưa ra danh sách các lệnh được hỗ trợ. Trong trường hợp của tôi, họ là:
% busybox --help

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as.
