Usage: cat xy.csv | sum-distinct I use this script when counting the response times of a web service per minute. Often I take the access logs, sed/awk/cut the time of day and the milliseconds so that my "x" is the HH:MM and the "Y" is the duration. When done, I have the total duration per minute (sorted lexically). It's perl as I often need to bring this to new servers which often are "bare bones".
