I read that with wget you can retrieve content from web servers, but im little confused about its usage. I downloaded it from the GNU Project website and i know you have to type command lines in order to execute it. I read all the documentation but they forgot the most important part. WHERE do i enter these command lines. I tried in both command.exe and cmd.exe by typing the command wget anysite.com but i get an error so it seems like you dont enter the command there so i would appreciate if you tell me where. Im using windows vista. Also, if you can please tell me if this programa REALLY retrieve ALL web content or just shows imagaes and html files that are linked which is useless because i want to see all files an directories like php files, etc.
It's just a download program. You can't use it to download a PHP file from a server so that you can read the PHP code (unless you're trying to get it from a site like mine which is configured to allow people to view my PHP source). You can't download anything with it that you can't already download with a web browser.
No. You can't view anything on a properly configured server that you have not been given permission to do so. If you want to see the contents of a directory, then just put its URL in your browser. If you don't see a listing of its contents then the owner doesn't want you to see it and there's nothing you can do about it.
