First off, you'll want to post code in a way that keeps the
formatting, otherwise it becomes very hard to read.

But the immediate problem here is that Popen takes an array of command
arguments, NOT a shell command line. You cannot invoke ls and pipe it
into awk this way.

Don't think like a shell script. Python has very good
directory-listing functionality, and you will very very seldom need to
shell out to pipelines. Figure out what you actually need to learn
from the directory listing and get that information directly, rather
than trying to use two external commands and text parsing. It's far
FAR easier, cleaner, and safer that way.

As a quick fix try

process = subprocess.Popen(
cmd # no list
shell=True,
... # other args as above
)

advice
