Similar question to How to get a udp response with netcat except the OP was satisfied with using nc interactively (and I don't have the reputation to comment yet!)
I need to be able to code some bash script and deal with the response. How should the code below be changed to get the response in the file response.txt or otherwise capture the response for later lines of code in bash?
echo "request" | nc -u 22.214.171.124 9999 > response.txt
The server might take a few seconds or even minutes to generate the response and reply. When I try the following, I'm returned to the command prompt immediately and response.txt is empty.
echo "request" | nc -u 126.96.36.199 9999 | tee response.txt
(I did indeed confirm that running nc -u 188.8.131.52 9999 and typing "request" on a line by itself returns the expected response. But how to capture it?)
Thanks in advance!
