Nohup not returns to the prompt

Hi i have a script and i ma running that via nohup and &.
I am expecting that to return to the user prompt immediately.
But it's not returning and returns only after i press ctrl+c.
i am invoking the script as follow as :
Code:
nohup ./script args &

Code:
$ nohup: appending output to `nohup.out'

How to make that to return it to the user prompt immediately rather than displaying the above message and waiting?

Thanks

It's working. But what makes the difference and how it works?

Thanks,

The only difference is redirecting the message to the text file. Otherwise they act the same.

I think it is actually returning control to your prompt, especially since you put & after it, but it prints (once) over your prompt before it does, causing confusion.

Actually, the message is not redirected; the message is simply not generated.

That informational message is written by nohup to stderr only when stdout is a terminal, forcing it to choose a new destination for stdout (and possibly stderr, if it to is a terminal).
