headsort: streaming sort + 2x faster than gnu sort
headsort sorts files by line and fields. Options can pick field order and etc.
In general headsort can sort in 1/2 the time sort(1) (mergesort) does in situations involving either pipes or mult column selection; less than 1/2 with both. Best case was about opposite that of sort(1)*.
NEW* hsort main algorithm speed improvement (applies to all; 27,29,31).
I want to write base libraries to easily parse TSV files.
Most of thinks can be done with unix cmd lines, but here I will also deal with headed files and try to managed some metadata.
Else goals are reorder, sort, filter, extract, merge, ...
I'll also try to develop class to have a general API, regardless the language.
It's a try !

This project provides a set of libraries written in Java to easily manipulate Multi-Criteria Decision Aid (MCDA) concepts, especially related to outranking methods, and XMCDA files.
Welcome to the StarFiles Homepage!
This application is designed to sort FITS star image files taken by professional astronomers at observatories. The application sorts the files by their image type: Bias, Dark, Flat, and Object. The Flat and Object images are sorted by filters U, B, V, R, and I. The application allows the user to create and save a profile of a given observatory's FITS header format, for future sorting use.
