uci COMMAND [ARGUMENTS...]

uci (Unified Configuration Interface) manages OpenWrt configuration files. It provides a standardized way to read and modify the UCI configuration format used throughout OpenWrt.
Configuration is organized into files, sections, and options. Changes are staged and must be committed to take effect. The revert command discards uncommitted changes.

OpenWrt specific. Changes require commit to apply. Some services need restart after configuration changes. Invalid configuration can break network access.

UCI was developed for OpenWrt to provide a consistent configuration interface across all system services, simplifying administration of embedded routers and devices.
