So why the double fork? POSIX.1-2008 Section 11.1.3, "The Controlling Terminal", has the answer (emphasis added):
If a process which is not a session leader opens a terminal file, or the O_NOCTTY option is used on open , then that terminal shall not become the controlling terminal of the calling process. One difficulty with doing a double fork is that the parent can t easily get the PID of the grandchild process the fork call returns the child s PID to the parent, so it s easy to get the PID of the child process, but not so easy to get the PID of the grandchild process.

What is the reason for performing a double fork when creating a daemon?
I'm trying to create a daemon in python. I've found the following question, which has some good resources in it which I am currently following, but I'm curious as to why a double fork is necessary. I've scratched around google and found plenty of resources declaring that one is necessary, but not why. Some mention that it is to prevent the daemon from acquiring a controlling terminal. How would it do this without the second fork? What are the repercussions?

Jan 13, 2016 at 5:18 @CraigMcQueen I am in need of knowing the grandchild processes PID. What is the way to do this? Sep 18 at 15:24@CalebK using some sort of IPC (inter-process communication). Before the fork, you could create a pipe, then the child could send the grandchild's PID through the pipe back to the parent.

Reviews for "Buy Mr. Clean Magic Erasers in Bulk and Save"
1. Samantha - 2 stars - I was so disappointed with the Mr. Clean Magic Eraser wholesale price. I had heard so many good things about this product and was excited to try it. However, I found that it didn't live up to the hype. I had to scrub really hard to remove any stains or marks, and even then, it didn't completely clean the surface. I also noticed that the eraser didn't last very long, and I ended up needing to use multiple erasers for just one cleaning job. Overall, I don't think it's worth the wholesale price and I won't be purchasing it again.
2. Michael - 1 star - I was highly dissatisfied with the Mr. Clean Magic Eraser wholesale price. I had high expectations for this product, but it fell short in every aspect. The eraser disintegrated after just a few uses, making it a poor value for the cost. Additionally, it didn't effectively remove tough stains or marks as advertised. I found myself having to use additional cleaning products in conjunction with the eraser to achieve the desired results. Overall, I would not recommend purchasing the Mr. Clean Magic Eraser at the wholesale price, as it simply doesn't live up to its claims.
3. Emily - 2 stars - I was initially excited to try the Mr. Clean Magic Eraser at the wholesale price, but unfortunately, it didn't live up to my expectations. The eraser quickly wore down after just a couple of uses, and I found myself having to constantly replace it. It also didn't effectively remove stubborn marks and stains like I had hoped. I ended up needing to scrub with a lot of force to achieve any noticeable results. For the wholesale price, I expected a more durable and efficient product. I won't be repurchasing it.
4. Marcus - 3 stars - The Mr. Clean Magic Eraser at the wholesale price was just okay in my opinion. I wasn't blown away by its cleaning abilities, but it did an average job. However, I did find that the eraser wore down quite quickly, forcing me to use multiple erasers for one cleaning task. It also didn't work as effectively on tougher stains and marks. While it wasn't terrible, I don't think it's worth the wholesale price and I would probably opt for a different cleaning product next time.
