It appears that du and tar use a different pattern language for their --exclude-from option. I was trying to predict the size of a backup that would be performed with tar, and came across a discrepency.
df reports that I'm using 2882M. tar --exclude-from says that the backup is 2722M. du with my tar-friendly exclude from reports that I'm using 2942M. du without any exclude file reports that I'm using exactly: 2942M. The options have the same name, and both commands hail from gnu.org, so shouldn't they cooperate? Linux 2.4.18, ext3, Debian Unstable, fileutils 4.1, tar 1.13.25. My exclude file is attached. -- Jacob Elder http://www.lucidpark.net/
