| numsum [-iIcdhrsvxy] (Input on STDIN from pipeline.)
numsum [-iIcdhrsvxy] (Input on STDIN. Use Ctrl-D to stop.)
numsum will take all the numbers on stdin and return the sum of those numbers. Currently it only processes the first number on each line (unless when using the -x option). Besides positive numbers, it also handles negative numbers and numbers with decimals.
-i Only return the integer portion of the final sum.
-I Only return the decimal portion of the final sum.
-c Print out the sum of each column.
-r Print out the sum of each row.
-x <n> Specify a comma separated list of columns to print.
-y <n> Specify a comma separated list of rows to print.
-s <string> Specify a string to use as a separator for columns.
This defaults to be consecutive whitespace (\s+).
-h Help: You're looking at it.
-V Increase verbosity.
-d Debug mode. For developers
-q Quiet mode, don't print any warnings.
Simply add up the numbers in a file.
