How to make
nc client on OS X Mavericks keep socket open and read data until server disconnects the socket?
I want to send data to a server through
nc and then use the response. Problem is that
nc disconnects the socket after the data has been sent, without waiting for the server's response.
This will just write the data then exit:
$ echo "my instruction here" | nc 127.0.0.1 $MY_PORT
This will write the data and then not exit even though the server has disconnected:
$ cat <(echo "my instruction here") - | nc 127.0.0.1 $MY_PORT
nc man page on OS X Mavericks have the following example for sending a
HTTP GET request and printing the response, but it's not working. It just sends the request then exits without waiting for the server's response. Seems like the man page's information is incorrect?
$ echo -n "GET / HTTP/1.0\r\n\r\n" | nc host.example.com 80
