Running command in background

[klim2]

Hi Everybody,
could you please tell me why the following command doesn't release terminal:
find / filename > findout &

I expected the command to release my terminal and redirect output to file findout.
Instead the output was still displayed on the terminal and I didn't get the command prompt.

Thanks
Klim

find / | grep filename &> findout &

&> redirects all to findout,
i personally use pipe grep for looking for filename but you can also use

find / -name "filename"

To release the terminal, enclose the entire command in parentheses:

(find / filename > findout &)

[klim2]

@qamelian, not sure what I did wrong but the parentheses didn't help. I still got the output sent to the terminal, not findout file.

@3246251196, thanks! the following command did the trick:

find / -name "filename" &> findout &

What is interesting that only one background process was started. I still can't explain to myself why it works.
Is it documented somewhere?

There is only one process running, it is "find". The &> redirects both stdout and stderr to the same file. You can have more I/O streams than that if you set it up explicitly, but by default you have stdout and sterr for your programs' output.
