rust-parallel
A fast Rust/Tokio command-line utility for running shell commands in parallel with a GNU Parallel/xargs-like interface.
What is rust-parallel?
rust-parallel is a command-line application written in Rust that runs shell commands in parallel, aggregating their outputs efficiently. It solves the problem of slow sequential command execution by leveraging asynchronous processing to significantly speed up batch operations, making it ideal for tasks like file processing, data transformation, and system administration scripts.
System administrators, DevOps engineers, and developers who need to execute multiple shell commands concurrently, especially those working with large datasets, batch processing, or automation scripts.
Developers choose rust-parallel for its exceptional speed (over 10x faster than GNU Parallel), familiar interface, and rich feature set including ordered output, progress bars, and flexible input handling, all built on Rust's reliability and async capabilities.
Overview
