I am fresh programmer on shell script. i want to do some automation using nc command via shell scripting. I need to run certain command after connecting server with selected port using nc . server is listening on connected port. we can get prompt to pass content while running from terminal. but i need to pass content many times. So I made a shell file which is containing following code but response is not coming 

#!/bin/bash  
#test.sh

function nc_input { echo "ABCD,R,1,5151670,512173140137353,01141456843,0" }

nc_input | nc 10.200.16.223 7913
