eselect is a tool for administration and configuration on Gentoo systems. It will modify the system’s behavior and should be used with care by the system administrator. eselect is a modular framework for writing configuration utilities. It consists of:

  • A main program called eselect.
  • Various modules (
  • .eselect files) which carry out different tasks.
  • Several libraries which help ensure consistent behavior and simplify the creation of new modules.

A module provides several actions. Actions typically either display some information (list and show actions are common) or update the system somehow (for example, set and update). Each module also provides help and usage actions which explain how to use the module.
