说明
yes outputs a string repeatedly until killed or the pipe closes. By default, it outputs "y" followed by a newline, endlessly. The primary use is piping to commands that ask for confirmation, automatically answering "y" (or any specified response) to all prompts. This is useful for scripting commands that don't have native batch/quiet modes. When the receiving command closes its stdin (by exiting), yes terminates automatically due to the broken pipe. Without piping, yes runs indefinitely and must be interrupted with Ctrl+C.
