tldr (from the acronym "too long didn't read"), is a succinct help system for CLI commands. Complimentary to man pages and "--info" documentation, it provides quick reference and can be a handy way to jog memory about basic command functionality.


There are two implementations of tldr in the GURU ebuild repository, app-text/tldr, and app-misc/tealdeer.

See the GURU guide, eselect repository and emerge for how to install.
