How to avoid os.system() printing out return value in python

Question

I\'m using Python to call bash to execute another bash script:

begin = int(sys.argv[1])
result = os.system(\"/tesladata/isetools/cdISE.bash %s\" %begin)
         


        

Answer 1

You can just throw away any output by piping to /dev/null.

begin = int(sys.argv[1])
result = os.system("/tesladata/isetools/cdISE.bash %s > /dev/null" %begin)

If you don't want to display errors either, change the > to 2&> to discard stderr as well.
