With the release of Red Hat Enterprise Linux 10 (RHEL 10), Red Hat has taken another significant step toward intelligent automation. Alongside features like Image Mode, post-quantum cryptography, and enhanced kernel live patching, one of the most exciting additions is RHEL Lightspeed, an AI-powered assistant that lives right inside your terminal.
Lightspeed acts as your AI command-line companion, designed to help system administrators and developers understand commands, resolve issues, and configure systems faster, all from within the familiar RHEL shell environment.
In this blog, we’ll explore what RHEL Lightspeed is, how to enable and use it, and why it can transform the way we interact with enterprise Linux systems.
What is RHEL Lightspeed?
RHEL Lightspeed is Red Hat’s built-in AI assistance layer that provides intelligent guidance on Linux administration tasks. It’s trained using Red Hat documentation, knowledge base (KB) articles, and best practices, allowing you to query the system for help directly, without leaving the terminal or searching external sites.
Think of it as having a Red Hat Support engineer or documentation expert sitting beside you, available 24/7, interpreting your intent and suggesting verified solutions.
Lightspeed can:
How to Enable and Access RHEL Lightspeed
RHEL Lightspeed is available in RHEL 9.6 and 10 Beta and GA releases for systems registered with Red Hat Subscription Manager and enabling Red Hat Insights.
1. Register Your System
Before you can use Lightspeed, your RHEL system must be registered with Red Hat Subscription Manager to ensure it is recognised and properly licensed for Red Hat services:
sudo subscription-manager register
Next, enable Red Hat Insights, which allows Lightspeed to provide contextaware, personalised guidance based on your system’s configuration and telemetry:
sudo insights-client –register
Connecting to the Red Hat cloud console enables Lightspeed to analyse your environment securely and deliver tailored command explanations, troubleshooting help, and relevant recommendations.
2. Install Lightspeed
Once your system is registered and Insights is enabled, you’re ready to install the Lightspeed commandline assistant. This package provides the c utility that allows you to interact with the AI directly from your terminal.
Run the following command to install Lightspeed and its required dependencies:
sudo dnf install -y command-line-assistant
During installation, you’ll see several supporting packages being pulled in, these enable the assistant to communicate securely with Red Hat services and integrate with your system environment.
3. Verify and Start Asking Questions
With Lightspeed installed, you can immediately begin querying the AI from the terminal using the c command:
$ c “How to enable and configure SELinux?”
Lightspeed will return a detailed explanation:
Or you can get a quick explanation of a command:
$ c ” explain systemctl isolate multi-user.target”
You’ll receive a breakdown of what the command does, when to use it, and how it affects your system
Lightspeed’s answers typically include:
This makes it incredibly useful not just for solving problems, but for learning as you go.
For example:
Practical Use Cases
Here are a few real-world examples where Lightspeed can save time:
Why Lightspeed Matters
As enterprise Linux environments become more distributed and hybrid, teams are under constant pressure to manage complexity while ensuring compliance and uptime.
RHEL Lightspeed bridges the gap between documentation and real-time execution:
Tips for Effective Usage
What’s Next
Red Hat has hinted at future integration between Lightspeed and Ansible Lightspeed, where AI will be able to suggest automation playbooks, explain YAML tasks, and even auto-generate Ansible roles from terminal queries.
This convergence of AI, Automation and Linux marks a major step toward self-healing and self-optimizing infrastructure, something every enterprise IT team should prepare for.
Final Thoughts
RHEL Lightspeed is more than a novelty, it’s the beginning of a smarter Linux experience. By embedding AI directly into the command-line interface (CLI), Red Hat empowers administrators to learn, troubleshoot, and execute faster while maintaining control and traceability.
Whether you’re managing a single RHEL server or a fleet of enterprise systems across hybrid environments, start experimenting with Lightspeed today.
You might just find that your command line has become your new AI mentor.
