Re: "tee" process being killed

Hi,

When I use

sudo python -u server.py 2>&1 > server_log.dat & 

there is some output that is printed to the terminal not the log file:

[ec2-user@ip-10-0-0-117 server]$ sudo python -u server.py 2>&1 > 
server_log.dat &
[1] 15218
[ec2-user@ip-10-0-0-117 server]$ [13/Nov/2017:10:21:35] ENGINE Bus STARTING
[13/Nov/2017:10:21:35] ENGINE Started monitor thread '_TimeoutMonitor'.
[13/Nov/2017:10:21:35] ENGINE Started monitor thread 'Autoreloader'.

I am not sure if I run cherrypy in auto update mode. How do I check that?

Andrew
