Linux Swarm Script
This article is regarding a script that I’ve never gotten to work properly on OpenBSD, and only works correctly (currently) in Linux. This script is used to access and run commands across multiple servers in parallel.
Edit: This script now works fine on OpenBSD, with the only requirement being to install the flock package! Also, this script is actively being ported to being 100% POSIX compliant, which should enable any shell to run it without issue.
