parallel

brew install parallel v20260522 GPL-3.0-or-later

GNU shell command parallelization utility for running multiple jobs in parallel across cores and machines.

Why you might care

Distributes shell commands and scripts efficiently across available CPUs or remote hosts, making it ideal for batch processing and embarrassingly-parallel workloads. Unlike xargs, parallel handles complex argument substitution and job distribution with built-in remote execution. A single-tool replacement for many ad-hoc shell loops and background process management.
