NAME

       numsum - numsum program file

SYNOPSIS

       numsum [-iIcdhrsvxy] <FILE>

       | numsum [-iIcdhrsvxy]	(Input on STDIN from pipeline.)

       numsum [-iIcdhrsvxy]	(Input on STDIN.  Use Ctrl-D to stop.)

DESCRIPTION

       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.
       Besides positive numbers, it also handles negative numbers and numbers with decimals.

OPTIONS

	   -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 seperated list of columns to print.
	   -y <n>  Specify a comma seperated list of rows to print.

	   -s <string> Specify a string to use as a seperator 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.

EXAMPLES

       Simply add up the numbers in a file.
	   $ numsum numbers.txt
	   4315

       Enter your own numbers on STDIN. The last number is the answer.
	   $ numsum
	   4
	   21
	   98
	   100
	   223

       Use it in a command pipeline.
	   $ ls -1s | grep .mp3 | numsum -c -x 5
	   72288

       Add up the total byte count in a http log file.
	   $ cat access_log | awk {'print $10'} numsum

	   or

	   5 10 15 20 25
	   $ numsum -c columns
	   15 40 65 90 115

       Add up the 1st, 2nd and 5th columns only.
