numsum - numsum program file

       numsum is part of the num-utils package, which is copyrighted by Suso Banderas and released under the GPL

         Developers can read the GOALS file and contact me about providing

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.

       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

           numsum -c -x 10 access_log

       Add up the columns of numbers of a file.

           $ cat columns
           1 6 11 16 21
           2 7 12 17 22
           3 8 13 18 23
           4 9 14 19 24
           5 10 15 20 25
           $ numsum -c columns
           15 40 65 90 115

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

           $ numsum -c -x 1,2,5 columns
           15 40 115

       Add up the rows of numbers of a file.

            $ numsum -r columns
            55
            60
            65
            70
            75

       Add up the 2nd and 4th rows.

            $ numsum -r -y 2,4 columns
            60
            70
