Hi there,

To answer the later questions: that's the bit you're missing -- disk
usage *per user*.

>>>  find ./ -printf "%u  %k/\n"| awk '{user[$1]+=$2}; END{ for( i in user)
>>> print i " " user[i]}'

It does the sums based on the file owner and 1 kB disk blocks.

Divide by a million.

Or by 1024*1024, depending on how accurate you want to be.

Replace the final

user[i]

with

user[i]/1048576

(or, as Nexor said, 2^20)

Output will be printed according to CONVFMT, which defaults to "%.6g"
-- set that (for example, in the END block) to decide what rounding
and decimal places you want to see.

It looks like a kind of advisory quota system, on shared writable space.
