title: How to run a command in the background and get no output?
body: <p>I wrote two shell scripts <code>a.sh</code> and <code>b.sh</code>. In <code>a.sh</code> and <code>b.sh</code> I have a infinite for loop and they print some output to the terminal. I want to write another script which calls both <code>a.sh</code> and <code>b.sh</code> but I want the user to regain control of the terminal immediately, instead of having the script run infinitely and I want to hide the output in terminal.</p>
