The xyz.sh wrapper adds no telemetry and does not perform hidden actions. You can read the full source on the page or with curl -fsSL xyz.sh/ .sh before running it. Piping a remote script to bash is still a risk — review the source first. The test is performed by Ookla's official CLI, which contacts Ookla servers and has its own terms and privacy policy: https://www.speedtest.net/terms and https://www.speedtest.net/about/privacy. xyz.sh will not silently add the accept flags before you confirm, and it adds no extra telemetry.

Which operating systems are supported?

Declared support: Debian, Ubuntu, CentOS, Rocky Linux, and AlmaLinux. The script detects the distribution and asks before continuing on an unrecognized OS. Syntax was checked with bash -n and ShellCheck; installer scripts have not been end-to-end verified on every listed distribution.

Yes. Run it as root or via sudo bash. The script exits with a message if it is not root.

Can I install without running a test?

Yes: curl -fsSL xyz.sh/speedtest | bash -s -- --install-only.

VPS Speedtest Tutorial (Official Ookla CLI)

This tutorial shows how to install the official Ookla Speedtest CLI with xyz.sh/speedtest and run one test. The test contacts Ookla servers and is subject to Ookla's own terms.

Steps

As root, run: curl -fsSL xyz.sh/speedtest | bash

If the official CLI is missing, the script downloads the official architecture-specific tarball from https://install.speedtest.net/app/cli (currently 1.2.0), verifies its SHA256, and installs it to /usr/local/bin/speedtest. No apt/dnf repository is added.

Before the test, it prints links to Ookla's license and privacy policy. Only after you confirm (or use -y after reading the notice) does it run speedtest --accept-license --accept-gdpr. See https://www.speedtest.net/terms and https://www.speedtest.net/about/privacy.

To install without testing: bash -s -- --install-only. To uninstall: bash -s -- --uninstall.

Uninstall

Run curl -fsSL xyz.sh/speedtest | bash -s -- --uninstall, or delete /usr/local/bin/speedtest. License acceptance may be stored in ~/.config/ookla. If an older package-manager install still exists, also run apt-get/dnf/yum remove speedtest.
