Question require detailed description for df -k command
Hi,

I have used df -k always just to check the % of disk space left.

Recently i discovered that the sum availabl space and used space is not equal to 1K-blocks.

Can anyone explain me the reason for this difference.

Thanks.

Your filesystem may reserve part of the filesystem for a particular purpose. For example ext3/4 reserves 5% for the root user by default.

Please give a detailed example, showing what command(s) you typed, what the answer was, and what you think is wrong. Please mention the Operating System and version and the type of filesystem (e.g. ufs, vxfs). Were you logged in as user "root".

On some versions of unix I have seen the free space reported quite differently according to whether you are logged in as "root" or as a basic user. The difference is usually 10% of the capacity of the filesystem but is configurable.

Let's see your numbers.
