Different output for df -h and du for /tmp

October 31, 2007

There were some process running which were referring to the files in tmp, even though the files are deleted and that was causing the difference in output for df -h and du for /tmp

To kill those processes:

for i in `lsof | grep deleted | grep tmp |awk {'print $2'}`; do kill -9 $i; done
