How to join multiple processes in shell?

Question

So I've made a small c++ binary to connect to do a command on a server to stress test it, so i started working on the following shell script:

#!/bin/bash

for ((  i = 0 ;  i <= 15;  i++  ))
do
   ./mycppbinary test 1 &
done

Now, I also happen to want to time how long all the processes take to execute. I suppose I'll have to do a time command on each of these processes?

Is it possible to join those processes, as if they're a thread?

Answer 1

You don't join them, you wait on them. At lest in bash, and probably other shells with job control.
