Public bug reported:
According to the man page this is the expected output below.
OPTIONS
-c Get a current fragmentation count and an ideal fragmentation
count, and calculate fragmentation score based on them. By see‐
ing this score, we can determine whether we should execute
e4defrag to target. When used with -v option, the current frag‐
mentation count and the ideal fragmentation count are printed
for each file.
Also this option outputs the average data size in one extent. If
you see it, you'll find the file has ideal extents or not. Note
that the maximum extent size is 131072KB in ext4 filesystem (if
block size is 4KB).
If this option is specified, target is never defragmented.
I am attaching a screenshot of my output which is not what I expected.
This may not be a bug but it is not very informational.
