tldr

Written entirely in /bin/sh with only curl and unzip as dependencies, ensuring it runs on any Unix-like system from Linux to FreeBSD, as emphasized in the README for universal client compatibility.

Automatically caches tldr pages locally to reduce network requests, with configurable refresh intervals via the -u flag, improving performance for frequent use without hitting GitHub ratelimits.

Supports environment variables to customize text colors and styles for different sections (e.g., TLDR_HEADER, TLDR_CODE), allowing personalized documentation display as detailed in the Customization section.

Allows overriding language detection with -L and filtering commands by platform with -p, enabling access to relevant pages for specific systems and preferred languages, per the usage examples.
