Subject: Windows 2008 Server: Reading Text File with Ruby.

Hello -
New Ruby user here.
I was wondering if you could point me in the right direction:

- I save the output of a WMIC query to a temp text file on Windows 2008
using Ruby:

system("wmic MEMORYCHIP get CAPACITY /VALUE > tmp")

- Next, I try to read this file back in order to extract a value from
the output:

contents = File.open('tmp', 'r:') { |f| f.read }

However, when I run this in irb, the file is imported with the following
leading characters: \x00 and others.  If I open the actual tmp file in
Windows, it displays the correct text.

Is there a way to just import that text only? Is this something to do
with encoding?

Thank you for your help.

Here is the entire session in irb:

irb(main):002:0> system("wmic MEMORYCHIP get CAPACITY /VALUE >
tmp")
=> true
irb(main):003:0> contents = File.open('tmp', 'r:') { |f| f.read }
=>
"\xFF\xFE\n\x00\n\x00N\x00o\x00d\x00e\x00,\x00C\x00a\x00p\x00a\x00c\x00i\x00t
\x00y\x00\n\x00\n\x00P\x00S\x00,\x008\x005\x008\x009\x009\x003\x004\x005\x009\x0
02\x00"
irb(main):004:0>
