将nohup重定向到脚本上的stdout

Question

I have a .sh script that via nohup runs a lot of Python scripts.

I use nohup to run them in the background and avoid neccesary enter pressing when the " nohup: ignoring input and appending output to 'nohup.out' " message appears.

nohup python script2.py 2> /dev/null &
nohup python script2.py 2> /dev/null &
[...]

When I run this .sh , I get the two Python scripts running in the background, ok.

This Python scripts generate a log file, which I deriver to std.stdout :

stream_config = logging.StreamHandler(sys.stdout)  <-- here
stream_config.setFormatter(formatter)
importer_logger.addHandler(stream_config)  

Due to my implementation, I want to launch those nohup but sending the stdout to to PID 1

I can do this easily without using nohup as follows:

python tester.py > /proc/1/fd/1

But how can I combine that " don't press enter to continue " and " deriver the file to stdout "?

I tried these with no luck:

nohup python tester.py > /proc/1/fd/1 2> /dev/null &
nohup python tester.py 2> /proc/1/fd/1 &

Thanks in advance.

Answer 1

You can fix your command by using the shell to indirectly start your program so that you can redirect its output rather than the output of nohup:

nohup bash -c "exec python tester.py > /proc/1/fd/1" 2> /dev/null &

This isn't the best option but it at least corrects the issue that made your attempts fail.
