Q:

PHP exec() nohup with redirect

I am trying to execute a command with exec() and redirecting stdout and stderr to a file. 
exec("nohup python main.py -i 1 > /var/scripts/logs/1_out.log 2>&1 &");
It will create the file but it will not print anything to it. 
If I run the command in a terminal everything outputs without a problem. 

A:

Got it working.  Python does its own output buffering which kept it from writing to the file.  Running it with the -u option disables this.  Final code looks like this:
exec("nohup python -u main.py -i 1 > /var/scripts/logs/1_out.log 2>&1 </dev/null &");
Thanks.
