redirect wget output to stdout

The following command runs wget and sends the output to STDOUT instead of save to a file. Sometimes it useful for testing a URL's output.

wget -q -O - http://www.example.com/file.html

-q  - Turn off Wget's output. (don't print  http-headers ans wget information)
-O - Output file .  If - is used as file, documents will be printed to  standard output, disabling link conversion

Http request with telnet

How to do http request with telnet command: for testing www server or other reasons.
it's very simple, fo example


# telnet www.server.com 80GET / HTTP/1.0
 
don't forget twice  press enter (new line) after type "GET / HTTP/1.0"


or you can use HTTP 1.1 protocol,

# telnet www.server.com 80GET / HTTP/1.1
Host: www.server.com
 

or if you want to see only http-headers in response type HEAD instend of GET
