another way to look at this would be to use perl.

populate a hash 1 element at a time.
for each new line split it up into 2 variables (ie: $column1, $column2) then check the hash for an exhisting key that is equal to $column1.

if you dont have a key already then add $column1 and $column2 as the key value pair.

if it does exhists get the value for that key and add it to $column2.

once your files is done being read your hash will only have uniq keys. and your values will be added together.

NAME
theme -- create a web page from a template file SYNOPSIS
theme [-d root] [-E] [-f] [-o file] [-p pagename] [-t template] [-V] [textfile] DESCRIPTION
The theme utility takes a markdown(7)-formatted textfile (or stdin if not specified,) compiles it, and combines it with a template (page.theme by default) to produce a web page. If a path to the template is not specified, theme looks for page.theme in the current direc- tory, then each parent directory up to the document root (set with -d or, if unset, the root directory of the system.) If page.theme is found, theme copies it to the output, looking for <?theme action?> html tags and processing the embedded action as appropriate. theme processes the following actions: author Prints the author name(s) from the mkd_doc_author(3) function. body Prints the formatted markdown(7) input file. date Prints the date returned by mkd_doc_date(3) or, if none, the date the input file was last modified. dir Prints the directory part of the pagename include(file) Prints the contents of file. Markdown(7) translation will NOT be done on this file. source The filename part of the pagename. style Print any stylesheets (see mkd-extensions(7)) found in the input file. title Print the title returned by mkd_doc_title(3), or, if that does not exist, the source filename. version Print the version of discount(7) that this copy of theme was compiled with. If input is coming from a file and the output was not set with the -o option, writes the output to file-sans-text.html (if) file has a .text suffix, that will be stripped off and replaced with .html; otherwise a .html will be appended to the end of the filename.) The options are as follows: -d root Set the document root to root -E Normally theme will not expand <?theme body?> or <?theme toc?> in the <head> section, or <?theme style?> in the <body> section, but the -E option overrides this and allows expansions everywhere. -f Forcibly overwrite existing html files. -o filename Write the output to filename. -p path Set the pagename to path. -t filename Use filename as the template file. RETURN VALUES
The theme utility exits 0 on success, and >0 if an error occurs. SEE ALSO
