calling perl script that takes multiple input args in python

Question

Need help with integrating perl script with main python script.

I have a perl script by name: GetHostByVmname.pl

./GetHostByVmname.pl –server 10.0.1.191 –username Administrator –password P@ssword1 –vmname RHTest

I need to call above script from my python main script. Tried below, but doesn’t work:

param = "--server 10.0.1.191 --username Administrator --password P@ssword1 --vmname RHTest"


pipe = subprocess.Popen(["perl", "./GetHostByVmname.pl", param ], stdout=subprocess.PIPE)

Answer 1

You can either provide a shell command

Popen("./GetHostByVmname.pl –server 10.0.1.191 ...", ...)

Or an array where the the first element is the program and the rest are args.

Popen(["./GetHostByVmname.pl", "–server", "10.0.1.191", ... ], ...)

Currently, you are doing the equivalent of the following shell command:

perl ./GetHostByVmname.pl '–server 10.0.1.191 ...'
