[Tutor] Regular expressions...

[Spencer Parker]

I need to use a regular expression to get a couple of items for my python
script.  So far the script is running an 'ls' command to get a few items
that I need

I run an 'ls -sk /xen/domains2/machinename/disk.img'

Output

2454112 /xen/domains2/machinename/disk.img

Then I have it running an 'ls -lk /xen/domains2/machinename/disk.img

output:
-rw-r--r-- 1 root root 20980736 May  2 10:05
/xen/domains2/machinename/disk.img

Then I take those two number and divide them using the the used amount by
the actual size of the disk to get a percentage.  I take all of that data
and then stick it into a database.

What I need to get is just the size numbers using regular expressions.  I
tried using an index, but since the disk images can up to 20 gig and be as
low as 5 gig...the index changes.  I also need to get the 'machinename'
portion of the path as well to stick into the database.
