[X-Unix] re: quotas - My math stinks!

[Kevin Stevens]

I've deleted the original posts, but my initial take was that the OP  
may have been wrong in assuming that du is reporting 1K blocks.   
Unless you feed it a -k parameter, it reports in 512 byte blocks (OS X  
10.5), making his comparison off by a factor of two, which seems like  
the major problem.  Combining that with the 1000/1024 conversion  
difference should make everything even out.
