Suppress python warnings in system-wide or cron-wide

I have many python scripts that generate

/home/intranet/public_html/intranet/bin/utils.py:172: DeprecationWarning: os.popen4 is deprecated. Use the subprocess module. fin, fout = os.popen4(cmd)

and other warnings.

Is there any way to hide them in system or cron-wide?

Thanks!

Any other DeprecationWarning s? Run the script as follows:

 python -W ignore::DeprecationWarning thescript.py

If you want to ignore all warnings, use

 python -W ignore thescript.py

To ignore warnings in the system or in width, set the env variable PYTHONWARNINGS :

 PYTHONWARNINGS=ignore::DeprecationWarning # or PYTHONWARNINGS=ignore

Documentation: Option -W and PYTHONWARNINGS .

What version of python are you using? An invalid warning value should be ignored by default in 2.7.

If you don't want to output when running programs via cron, you just need to add >/dev/null 2>&1 to the end of the line of execution. This will redirect your normal output to zero, but also to errors.
