different free space result by "ls -a" and "df -k"
wavelet
I get differenct result for used space by "df -k" and "ls -al".
eg: /app2
what's the reason?
[flx06]-> df -k

ls and df are different commands that do different things.
Your ls command above may not have listed any files because there
are no files to list.
df -k is showing you total, used and free kilobytes of filesystem
space.
Nothing appears wrong with this based on the info you supplied.

At a guess I'd say you've got logging enabled on that filesystem.
man mount_ufs includes :
The log is allocated from free blocks on
the file system, and is sized approximately
1 Mbyte per 1 Gbyte of file system, up to a
maximum of 64 Mbytes.

Your FS is about 15Gb. The used space is around 15Mb, or 1Mb/Gb.

What, "ls -a" doesn't even show "." and ".." ? I don't think I believe
you. One would usually expect to see "lost+found" in a ufs filing system
as well.
In any case, the "df -k" output is not inconsistent with /app2 being
effectively empty. I would guess that you have ufs logging turned on
for it, and most of the usage you are seeing is the log area:
! The log is allocated from free blocks on the file system, and is
! sized approximately 1 Mbyte per 1 Gbyte of file system, up to a
! maximum of 64 Mbytes. [...]
