This section gives the technical explanation of why du and df sometimes report
different totals of disk space usage.
When a program that is running in the background writes to a file while the
process is running, the file to which this process is writing is deleted.
Running df and du shows a discrepancy in the amount of disk space usage. The
df command shows a higher value.作者: nagaregawa 时间: 2011-07-08 10:39
