Shell feedback If you don't have anything important to say, don't say anything. Commands generally output nothing if all went well. Commands set their 'exit status' (available via the $? variable) to zero on success, or non-zero on failure. Error and informational output is sent to stderr, not stdout. Example: $ rm /path/to/file $ echo $? 0 $
