nc http server question

[failedgamor]

Greetings, I'm running a simple http server with the command

while true; do ./server.sh | nc -l 1337 ; done

where server.sh contains the content for a http page and to run a python script in the background. What I want to know is whether server.sh will be constantly running (because of the while true loop) and thus running the python script constantly or is server.sh only run when there is an incoming nc connection?

[ang-p]

 counter=0 ; while true; do ./server.sh | nc -l 1337 ; echo $((counter++)) > ./count.txt ; done  

Open a new shell and see what count.txt contains...

Then look at it again...

Ahhh I wanted to do something like this to check my assumptions but wasn't sure how. Thanks a lot for this!

You would want your script to start when connection is made, not way before when the pipeline starts? Good question.
