"First you can add a file or directory name to the du
command to only find out the size a that particular file or
directory. For example du thefile will give me the size of the file
named thefile. The size is listed in KB but since there are no tags
or legend this is not readily apparent. To fix this add the -h
argument to the command so the line would look like du -h thefile.
"Next when looking at folders, if you only want to so the total
size of the parent folder and not have the sub directories listed,
add the -s argument to the command so the line would look like du
-hs thedirectory."
