How to start a new program from service(daemon)?
I am writing a simple python script that run as daemon on Ubuntu. I've successfully installed and started it by writing a valid init.d startup script.
The question is, can I(and how can I) invoke another program from that daemon process?
I've tried:
os.system("/bin/cp /tmp/somefileA /tmp/somefileB")
subprocess.call(["/bin/cp", "/tmp/somefileA", "/tmp/somefileB"])
# i'am not actually copying files, here i use cp for illustration because it doesn't involve stdin/stdout.
but both of them don't work(os.system is returning 256 and subprocess.call is returning 1) when the script is started by:
sudo service some_service start
But if I execute the script from terminal, it works well. Is this caused by some security policy? Thanks.
