How to just call a command and not get its output

Asked 2011-02-14T20:22:07.887

In Python, what is the shortest and the standard way of calling a command through subprocess but not bothering with its output.

I tried subprocess.call however it seems to return the output. I am not bothered with that, I just need to run the program silently without the output cluttering up the screen.

If it helps, I am callling pdflatex and my intention is just to call it.

python subprocess

In case your process produces significant amounts of output that you don't want to buffer in memory, you should redirect the output to the electronic trash can:

subprocess.run(["pdflatex", filename], stdout=subprocess.DEVNULL)

The special value DEVNULL indicates that the output is sent to the appropriate null device of your operating system (/dev/null on most OSes, nul on the other one).
