df+du=Total space allocated(for a file system)

Hi All,

Will df+du=Total space allocted for a file system??

Is the above correct. Please correct me If iam wrong.

In one my programs the above is not happening.

Please help me out.

Many thanks.

Regards,
Manas

df would give you total space allocated to the filesystem, used space and % of free space.
Whereas du would give you space listings directory wise.

df command should be enough to find out spcae details about a file system, unless you want it directory wise.

Hope it helps.

Thanks!
