How does linux shell remove the error message?

You can perform a redirection to shield the information, for example,>/dev/null 2> & 1

The Linux find command searches the directory to find out why there is no error with no permission.

If the user you are currently logged on to does not have the readable or executable permission for the searched directory

This error is reported.
