randselect

Crates.io GitHub Workflow Status (with event) Crates.io

This crate provides a simple command line utility for randomly selecting N files from a directory and copying or moving them to a target directory.

randselect operates (inefficiently) by generating a random permutation of the files in a given directory, then moving or copying the first N files in the resulting permutation to a target directory.

Could you do this with a few lines of bash? Almost certainly! This was just an excuse to write some Rust.

Install

You can install this with Cargo:

$ cargo install randselect
