I am writing a script that will continuously broadcast some data to port 30000, so a python udp listener can get the data and insert it into a table, from which I can draw that information and display on a web page.
So, I want to execute
echo -n -e "\x00\x00\x0A\x00 1 012601234512345\x00" | nc -w1 -u localhost 3000
in the bash script in a while loop.
This is the bash script I have so far:
#!/bin/bash echo 'Running Script' a=0 x=1 while [ $a -le 1 ] do echo 'echo -n -e "\x00\x00\x0A\x00 1 012601234'$x'12345\x00" | nc -w1 -u localhost 30000' sleep 5 let x=$(($x + 1)) done
The x variable is incrementing each time throughout the loop so the data changes each time.
At the moment I am thinking that rather than outputing that as a command to the terminal, it is just coming out as a string. I am very new to bash, and any help would be greatly appreciated.
