tldr

tldr is a community-maintained collection of simplified help pages for console commands. Instead of overwhelming yourself with man page documentation, tldr provides focused, practical examples that show you how to use the most common features of a tool.

tldr pages are written in Markdown and available for commands across multiple platforms including Unix, Linux, macOS, FreeBSD, NetBSD, OpenBSD, SunOS, Android, Windows, Cisco IOS, and DOS. The project supports multiple client implementations (like tealdeer) and can be used from the web at at https://tldr.inbrowser.app with offline PWA support.

tldr tar

# View the page for a command with examples.

# Update the pages (with some clients).

# Search for pages by keyword.
