I've been trying to figure out why some periodic scripts consume so much memory. I've narrowed it down to sort(1). At first, I thought the scripts were using it inefficiently, feeding it more data than was really needed. Then I discovered this: des@ds4 ~% (sleep 10 | sort) & (sleep 5 ; top -o res | grep sort) [1] 66024 66024 des 1 -8 5 54796K 52680K piperd 1 0:00 0.88% sort That's right - sort(1) consumes 50+ MB of memory doing *nothing*. (roughly half that on a 32-bit box) Something is rotten in the state of GNU... DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
