Fork and exec in bash

Question

How to implement fork and exec in bash?

Assume the script as

echo "Script starts" function_to_fork(){ sleep 5 echo "Hello" } echo "Script ends" 

Basically, I want this function to be called as a new process, such as in C, we use calls to fork and exec ..

From the script, the parent script is expected to end, and then "Hello" will be printed after 5 seconds.

Answer 1

 #!/usr/bin/bash function_to_fork() { ... } function_to_fork & # ... execution continues in parent process ... 

Answer 2

 (sleep 5; echo "Hello World") &
