Hello Matthew,

I've been looking for an easy command line tool like datamash for years. writing R code or complicated awk scripts for scratch work is unduly laborious.

Thank you for the kind words.
I'm glad to hear datamash is useful.

I noticed that  a cumulative sum function is missing from datamash. An immediate extension would be a cumulative distribution function (cumulative sum divided by total counts)  This is often extremely helpful in basic statistical exploration.

That's a good idea.
I will work on adding 'cumsum' operation to datamash.
