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 :

nohup ./script args &

$ nohup: appending output to `nohup.out'

try this...

nohup ./script args > /tmp/out.txt &

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).
