Newbie question - running a command and looking at output

[Dave]

I'm trying to run a command (arch -k) and check if the value returned is
'sun4v' or not.


kirkby@t2:[~] $ arch -k
sun4v

In fact, I want to do 3 three things

1) Check if the system is Solaris.
2) If it is Solaris, check if 'arch -k' prints 'sun4v'
3) If both 1 and 2 are true, copy a file.


Since arch -k is not supported on all systems, the test for Solaris must
be made first.

I have a test for Solaris (aka SunOS), which copies a file if the
systems is running Solaris:

import os, shutil

if os.uname()[0] == 'SunOS':
shutil.copy2('foo.c','bar.c')

How can I change that, so the copy is only performed if 'arch -k' prints
'sun4v'?

Actually, when I look at oluname, it does print sunnv:

('SunOS', 't2', '5.10', 'Generic_141414-02', 'sun4v')


I guess all I need to do is check for the value of os.uname()[4] too.
