What exactly do you want to compare?
Do you want to verify that the product numbers and amounts are identical
betwen the 2 files? So if one file had the following (scenario 1), it
would be considered identical to the other file (i.e. logically equal)?
122 - 2
236 - 3
335 - 44
124 - 02
Or, scenario 2, would you want the above to be considered different
(i.e. physically/binary equal)?
In case of scenario 1, you would just need to read in each file and parse
the data into hashes with the product id as the key and the quantity as
the value. Then just loop over a hash and verify that the same key in the
other hash has the same value.
In case of scenario 2, I'd look at using a diff utility or calculating a
checksum to validate that the files are identical.
