Excellent I used the ${ENTRY#*/} and it works not 100% how though?

It now looks like: -
du -sk ./* | sort -rn | head | \
while read SIZE ENTRY
  # if size > 1048576 then it is at least 1 GB big
  if [ ${SIZE} -gt 1048576 ]
    NEWSIZE=`echo "${SIZE}000 / 1048576" | bc | sed -e "s/\(...\)$/\.\1/"`
    printf "% 10s %s\n" "${NEWSIZE} GB" ${ENTRY#*/}
    # if size > 1024 then it is at least 1 MB big
  elif [ ${SIZE} -gt 1024 ]
    NEWSIZE=`echo "${SIZE}000 / 1024" | bc | sed -e "s/\(...\)$/\.\1/"`
    printf "% 10s %s\n" "${NEWSIZE} MB" ${ENTRY#*/}
    printf "% 10s %s\n" "${SIZE} KB" ${ENTRY#*/}

truncate - shrink or extend the size of a file to the specified size SYNOPSIS
Shrink or extend the size of each FILE to the specified size A FILE argument that does not exist is created. If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole) reads as zero bytes. Mandatory arguments to long options are mandatory for short options too. -c, --no-create do not create any files -o, --io-blocks treat SIZE as number of IO blocks instead of bytes -r, --reference=FILE use this FILE's size -s, --size=SIZE use this SIZE --help display this help and exit --version output version information and exit SIZE may be (or may be an integer optionally followed by) one of following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y. SIZE may also be prefixed by one of the following modifying characters: `+' extend by, `-' reduce by, `<' at most, `>' at least, `/' round down to multiple of, `%' round up to multiple of. Note that the -r and -s options are mutually exclusive. AUTHOR
