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. The associated modular framework for writing configuration utilities consists of:
- A main program called eselect.
- Various modules (.eselect files) that carry out different tasks.
- Several libraries which help to ensure consistent behavior and simplify the creation of new modules.
Each 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 that explain how to use the module.
To list all modules, run eselect without any arguments.
- Eselect/Repository — an eselect module for manipulating /etc/portage/repos.conf entries to third party repositories (also known as overlays).
- eselect fontconfig
- eselect php cli
