reorger

A small collection of tools for manipulating large collections of files. Most of these were written to help deal with image data sets for Machine Learning.

• split - Takes a glob pattern in the current directory and creates batches of 1000 files that match the glob pattern into subdirectories.
• unsplit - Reverts the split command by looking into all directories (with no further depth traversal) and moves them into the current directory. If a directory that is traversed ends up being empty, it will be removed.
• sample - Copies every n^th file that matches a glob pattern from the current directory into a new directory.
