Vista - Comparing files with compare-object

I've done everything I can think of to properly format a string to
compare between 2 files.

I've confirmed to my best of knowledge that one particular entry is
*exactly* the same in two files (same lenght, etc). However, I cannot
seem to get compare-object to find a match.

76# import-csv file1.csv|%{$_.'SN,CN'}|%{$_.replace(' (+)','')}|%{if($_
-match "some_user_removed"){$_}}|%{$_.length}
24
24
24
24
24
24
24
24
24
24
24
77# get-content file2.txt|%{$_.substring(13,56)}|%{$_.trimend()}|%{if($_
-match "some_user_removed"){$_}}|%{$_.length}
24

So above, I've confirmed (I think) that the string is exactly the same
lenght, however I can't get compare-object to indicate a match. One
file has 9,000 entries (lines), and the other has over 63,000.

I'm trying to get *only* the entries that match exactly between each
file. Something like this:

79# compare-object -ReferenceObject $(gc 1.txt) -DifferenceObject $(gc
2.txt) -includeequal -excludedifferent

InputObject SideIndicator
----------- -------------
test ==


80# gc 1.txt
test
testing
81# gc 2.txt
test

Any ideas? Gotchas I might be missing?

More info...

If I try to do an exact match for the -referenceobject and
-differenceobject, I can get a match.

This works:

85# compare-object -referenceobject $(get-content
1.txt|%{$_.substring(13,56)}|%{$_.trimend()}|%{if($_ -mat
ch "some_user_removed"){$_}}) -differenceobject $(import-csv
2.csv|%{$_.'SN,CN'}|%{$_.replace(' (+)','')}|%
{if($_ -match "some_user_removed"){$_}}) -includeequal -excludedifferent

InputObject SideIndicator
----------- -------------
some_user_removed ==

But again, this doesn't:

86# compare-object -referenceobject $(get-content
1.txt|%{$_.substring(13,56)}|%{$_.trimend()}) -difference
object $(import-csv 2.csv|%{$_.'SN,CN'}|%{$_.replace(' (+)','')})
-includeequal -excludedifferent
87#

My understanding is compare-object is not supposed to be a match line X
in file A with match line X in file B. In other words, line X in file A
can still be found to be a match with line Y in file B as long as the
content/string is the same.

I've found a workaround. It ain't pretty, but seems to work...

Did you try setting the -SyncWindow to something larger like 100?

No I didn't! That has to be the key... I'm comparing a 8,000 line file
to a 63,000 one...
