1) Have you tested everything? At first glance some of those look like they
won't work.
2) Whenever you repeat yourself, *especially* at this magnitude, you're
doing something seriously wrong - *especially* in Python.
*Completely-untestedly-and-super-quick-hackedly:*
import re, sys, subprocess, platform
class Command:
def __init__(self, command=None):
self.command = command
def __call__(self, *args):
command_list = [self.command] if self.command else []
command_list.extend(args)
print(subprocess.getoutput([command_list]))
def uname():
print(platform.uname())

print(subprocess.getoutput(lsof))

I wouldn't actually do it like this (I'd probably start with a dict and add
to a class programmatically), but this is a simple display of how one can
use classes and other meta-constructs to make things look nicer. It also
doesn't deal with forcing the number of arguments to be correct, but this
is demo material and so I leave that to you.
