This is a list of all Internet Relay Chat commands from IETF RFCs 1459 and 2812. Most IRC clients need commands to have a slash ("/") before the command. Angle brackets ("<" and ">") mean what's placed in the secondary field, not a literal part of the command. Settings encapsulated in square brackets ("[" and "]") are optional and override the command's defaults.

User commands

INFO

ISON
Syntax:
ISON <nicknames>

JOIN
Syntax:
JOIN <channels> [<keys>]
