From Gentoo Wiki
Jump to: navigation, search

This package can be used to search for files (or strings) provided by packages that are not yet installed, and optionally installs a little cronjob to update the database on the internet with the information that is available to be queried.

Installation

You can install app-portage/pfl with the following command:

root #emerge --ask app-portage/pfl

USE flags

USE flags for app-portage/pfl Searchable online file/package database for Gentoo

network-cron Adds a cron job which does a weekly submit of the package database

Usage

The database can be used online to search for files installed by ebuilds. Lets say you want to run glxgears but it isn't installed. Recently the program was removed from mesa itself, so you could search for glxgears online to find the related package: search online

Pfl is much quicker to search files (even if not installed locally), while equery is more powerful and gives more options to search.
