compare-object $a $b | where {$_.SideIndicator -eq "<="} 'i only want
results on the left-hand side



I got pc001 and pc004 ==> this works fine.

But if file1.txt contains thousand of records and file2.txt contains
hundreds of records, the results of the left-hand side INCLUDES some records
on the right hand side of the equations.

I m using v1. Is this an issue ?
