How to use linux-command: a Linux command reference guide
Updated · written with AI from the project's own documentation and checked against our catalogue data
linux-command is an open-source collection of over 600 Linux commands, with manual-style references, detailed explanations and learning material, published as a searchable website. This guide shows you how to use it as a quick lookup when you forget how a command works. By the end you will know how to search it in the browser, how to get a local copy of the repository, and where its limits are.

What linux-command is and who it suits
The project is a reference collection rather than a program you install. Its README describes it as a Linux command lookup tool that contains command manuals, detailed explanations, and learning material, and says the content comes from the web and community contributions.
It is best suited to people learning the command line who want readable explanations, developers who need a fast reminder of syntax and options, students preparing for Linux courses, and anyone who prefers a browser reference over reading man pages.
Open the linux-command website and search
The simplest way to use the project is through its website, which the README links at jaywcjlove.github.io/linux-command. Open the site in your browser, type the command you want to look up into the search box, and read the explanation for that command.
Because the site is a quick reference, use it when you need a reminder of what a command does or which options exist. For a full specification of a particular distribution or version, check that system's official documentation instead.
- Go to https://jaywcjlove.github.io/linux-command
- Enter a command name such as tar or grep into the search field
- Read the entry and compare it with your own system if something does not match
Clone the repository to work with the content locally
If you want a local copy of the material, the README gives a clone command. This downloads the repository so you can browse the Markdown source files on your own machine.
The repository is written in Markdown, so you can open its files in any text editor after cloning.
git clone https://github.com/jaywcjlove/linux-commandCheck important details before you rely on them
The author states that correctness of the content is not fully guaranteed, and that content comes partly from community contributions. Treat an entry as a starting point, not as the final word.
When a command matters, such as before running a destructive operation on a server, verify the syntax and options against your system's own manual page, for example by running man followed by the command name in a terminal.
- Do not assume every option or example is correct for your version of the command
- Use the reference for learning and recall, then confirm on your own system
