如何实现fork和exec在bash？

How do I implement fork and exec in bash?

让我们假设脚本

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

基本上我想该功能被称为C一样，我们使用fork和exec调用新的进程。

Basically I want that function to be called as new process like in C we use fork and exec calls..

从脚本预期母体脚本将结束，然后在5秒钟后，你好被打印。

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

推荐答案

使用的符号，就像你从shell会。

Use the ampersand just like you would from the shell.

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