High Quality Content by WIKIPEDIA articles! This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash ("/"). Angle brackets ("<" and ">") denote what`s placed in the encapsulated field, not a literal part of the command. Arguments encapsulated in square brackets ("") are optional and override the command`s defaults.
