Problem with 'filter' on large lists

[Terry Judd]

The filter command seems to be 'dodgy' when working with large lists 
(>100000) lines - ie gives different results to when the same data is 
broken up into a number of chunks. Has anyone else seen this or is it 
just me?

All I'm doing is some simple filtering of long lists of urls as in - 
filter theURLs with "*unimelb.edu.au"

Cheers,

Terry...
