Projects / num-utils


num-utils are a set of programs for dealing with numbers from the Unix command line. Much like the other command line utilities grep, awk, sort, cut, etc. these utilities work on numeric data from both standard in and data from files. The base utilities currently included are average, bound, interval, numgrep, numprocess, numsum, random, range, and round. If you work with pipelines on the command line, these tools will prove to be helpful.
