Call a function using nohup

Question

I am trying to call a function using nohup like this:

function1(){
    while true 
    do
        echo \"function1\"
        sleep 1
    done
}
         


        

Answer 1

Instead of using nohup, which is tailored for files, you can implement the same result like this:

(trap '' HUP INT
 while true
 do
   echo "function1"
   sleep 1
 done
) &1 1>nohup.out &

As I tend to launch these processes from a parent script and the parent script may do other work if the parent process is interrupted I want the child process to ignore the INT signal and keep on running.
