How To Install spawn on Fedora 34

spawn is Simple tool to run several Linux command-lines in parallel

Introduction

In this tutorial we learn how to install spawn on Fedora 34.

What is `spawn`

spawn is a simple parallel execution utility written to appeal to the Unix mindset. spawn reads shell command lines from stdin, one per line, and then executes them as maximum of N child processes in parallel, and waits for all of the children to exit. If a child process fails with a non-zero exit code, no new children are spawned. Then spawn waits for all existing children to exit and returns the failed exit code.

We can use yum or dnf to install spawn on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install spawn.
