How can I find the free space available on mounted points?

Question

I have raised this question previously but none of the solutions work on the mounted points. Neither du nor df work on the mounted points. Is there a way to find it out?

I don't understand what you mean by "doesn't work on the mount points". Change into the directory where you want to untar (if not already there) and execute:

df . | grep -v '^Filesystem' | awk 'NF=6{print $4}NF==5{print $3}{}'

The grep gets rid of the header and the awk prints out the kilobytes available for both split and no-split lines.

This is based on the following sort of output, you may have to adjust if your UNIX outputs something different:
