Does -q definitely turn off wget output logging?

Question

I currently have a shell script running on a linux server which is using wget in oder to download a remote web page. This in turn is executed by a cron job which is scheduled to run at certain times.

Can someone please confirm that adding in the -q option will not only stop all output being returned to the console, but will also stop all attempts by wget to write to the logs or to try and create a log file?

Answer 1

With -q option, wget itself should not output anything to either console nor the logfile specified by -o option, except for the case described by Michał. The logfile however will be created (if -o was supplied).

This however does not guarantee that no system daemons will notice the fact that wget was run - the network activity can be independently monitored by other tools.

Answer 2

no, --quiet will not guarantee no logs.

   * http.c (print_response_line): Changed to make responses always
   be logged, even in --quiet mode, if --server-response was
   specified. This is to bring http.c's handling of the situation
   in line with ftp.c's.
