usefull commands you might want to use: "df" and "du".

look at the mapages of the commands and see if this gets you any further.

Hint. This command gives the free disc space available in a filesystem containing a particular drectory. It works on most modern unix systems.
Code:
df -Pk /directory

You are using du (disk usage). This tells you nothing about the availability of space.

As was previously mentioned the df command will show free space.

If you don't have access to manpages, you can read them here.
