You got the syntax wrong:

GET http://www.linux.org/ HTTP/1.0<enter><enter>

But squid comes with such a client...called - imaginatively - client.

It's probably installed in the same directory as your squid binary:

${PATH}/client http://www.linux.org/

Run it without arguments to see how to set proxy hosts and ports (it
defaults to localhost:3128)
