Hi, all. I was copying two 6-GB DVD images yesterday, and while monitoring the copy progress, noticed that du would show a trend that *generally* headed toward the final files'' sizes, but on occasion would hop backward, thusly: root@hal-9000:/shared/ISOs# while true; do du * ; sleep 10; echo;done 1151808 SolidWorks_2008_32-bit.iso 1928784 SolidWorks_2008_64-bit.iso 1072032 SolidWorks_2008_32-bit.iso 1763280 SolidWorks_2008_64-bit.iso 1044384 SolidWorks_2008_32-bit.iso 2097152 SolidWorks_2008_64-bit.iso 1481248 SolidWorks_2008_32-bit.iso 2183184 SolidWorks_2008_64-bit.iso The images did copy, but I''m just curious as to what the mechanics were behind du''s seemingly non-linear reporting. (If it makes any difference, one copy was coming in via an ssh pipe from a different machine; the other was being copied from the local CD drive. Both were using "cat" to write the files.)
