Code:
awk '{ sum+=$9} {print} END {printf "%60s\n", "Total SGD " sum}' file

Code:
{sum+=$9}

Sums the value in column 9 for each record in file. Since no delimiter is specified, space is the default delimiter.

Code:
{print}

Prints each record on file as is, i.e. with no changes (can also be written as {print $0} )

Code:
END {printf "%60s\n", "Total SGD " sum}

After all records from file are read (END), print the string "Total SGD " together with total sum of column 9 (sum) right justified with width of 60 spaces (%60s) followed by new line (\n).
