rust-parallel – fast parallel command execution

rust-parallel is a command-line utility for executing commands concurrently and collecting their output. It provides an interface similar to GNU Parallel and xargs, with an emphasis on efficient process execution and predictable output handling.

The application uses the Tokio asynchronous runtime to manage concurrent commands. It can read input from standard input, files or command-line arguments, and automatically determines the available CPU parallelism.

Unlike basic parallel execution tools, rust-parallel can prevent output from different processes becoming interleaved. It also offers optional input-order preservation, progress reporting, command timeouts and configurable error handling.

This is free and open source software.

Key Features

• Execute multiple commands concurrently using Tokio.
• Read job arguments from standard input, files or command-line arguments.
• Automatically determine parallelism based on available CPUs.
• Manually configure the maximum number of concurrent jobs.
• Prevent output from separate processes becoming interleaved.
• Preserve input order when displaying command output.
• Transform input using variables and regular expressions.
• Pipe blocks of standard input to individual commands.
• Shell mode supports shell commands and functions.
• Optional terminal progress bar.
• Configure execution timeouts and error handling.
• Dry-run mode for inspecting commands before execution.
• Structured debug logging and command path caching.
• Cross-platform support – runs on Linux, macOS, and Windows.
