fork and exec in bash
提问by Abhijeet Rastogi
How do I implement fork and exec in bash?
如何在 bash 中实现 fork 和 exec？
Let us suppose script as
让我们假设脚本为
echo "Script starts"
function_to_fork(){
sleep 5
echo "Hello"
}
echo "Script ends"
Basically I want that function to be called as new process like in C we use fork and exec calls..
基本上我希望该函数被称为新进程，就像在 C 中我们使用 fork 和 exec 调用一样..
From the script it is expected that the parent script will end and then after 5 seconds, "Hello" is printed.
从脚本中，预计父脚本将结束，然后在 5 秒后打印“Hello”。

Use the ampersand just like you would from the shell.
像在 shell 中一样使用和号。
#!/usr/bin/bash
function_to_fork() {
...
}
function_to_fork &
# ... execution continues in parent process ...
