If you want to check quietly via    without the hassle of grep ing wget s output you can use   wget -q  http   blah meh com my path  -O  dev null   Works even on URLs with just a path but has the disadvantage that something s really downloaded so this is not recommended when checking big files for existence

There is the command line parameter --spider exactly for this  In this mode  wget does not download the files and its return value is zero if the resource was found and non-zero if it was not found  Try this  in your favorite shell    wget -q --spider address echo      Or if you want full output  leave the -q off  so just wget --spider address  -nv shows some output  but not as much as the default

You can use the following option to check for the files  wget --delete-after URL

If you are in a directory where only root have access to write in system  Then you can directly use  wget www example com wget-test using a standard user account  So it will hit the url but because of having no write permission file won t be saved   This method is working fine for me as i am using this method for a cronjob  Thanks   sthx
