New Commands

Command Description
<#chan> <message>
“Knock on the door” of an invite only channel. Will cause a notice to be sent to the channel so that others may see that you wish to enter.
<channel> <duration> <banmask>
Sets a timed ban. Allows channel operators and half-operators to set timed bans. A timed ban is set as though the user set it themselves, and removed by the server.The duration of the ban can be specified in the following format:
1w2d3h4m6s which indicates a ban of one week, two days, three hours, four minutes and six seconds.
Alternatively the ban may just be specified as a number of seconds. All timed bans appear in the banlist as normal bans and may be safely removed before their time is up.
Allows voiced users on a channel to devoice themselves.
<nick> <channel> [message]
Peaceful alternative to /kick. Allows channel ops to forcepart users from the channel, the user leaves with a “Remove by XXX: Remove message” part message, and a server notice is sent to the channel so you can distinguish people parting with artificial “Remove by XXX” messages.Note: May conflict with built-in mIRC /remove command. If so, use /FPART
<channel> <nick> [message]
The same as /REMOVE, except that <channel> and <nick> is switched around to match /KICK.
/SILENCE Standard IRC server side ignores with up to 32 entries. Examples:
    (display your current silence list)
  • /SILENCE + idiot!*@*
    (block messages by nickname idiot)
  • /SILENCE + *!*@*
    (block messages by anyone from
  • /SILENCE – joe!*@*
    (unblock the nickname joe)
Maintain a notify list of up to 32 nicknames. The WATCH command is a more efficient replacement for ISON. Usually this command is used directly by client software and not by users. Parameter ‘C’ is an extension used by mIRC to clear the watch list. Parameter ‘S’ is an extension also used by mIRC to query the watch list status. To add and remove nicks from the watch list, use the parameters +Nickname and -Nickname.
<pattern> [flags]
Looks up the information of users matching the range you provide. You may only /WHO nicknames in channels or on servers where you share a common channel with them, or ones which are not +i. The search-pattern may be a special sequence of
characters determined by the flags given below, or it may be one of a nickname, a channel, a hostmask, an ip address mask or a server mask.Optional Flags:
  • o
    Show online IRC operators matching the mask
  • u
    Unlimit the results past the maximum /who results value (IRC operators only)
  • r
    Show all users whos realnames match the mask. When this flag is set it overrides the meaning of the search-pattern, which must contain a glob pattern intended to match GEOCS (realname) fields.
  • h
    Show real hostnames rather than masked hostnames (IRC operators only)
  • m
    Search for all users with a given set of user modes. When this flag is set it overrides the meaning of the search-pattern, which must contain the mode sequence to search for, for example to find all users with +i and without +s, issue the command WHO +i-s m.
  • a
    Show all users who’s away message matches the given mask
  • p
    Show all users who are connected on the given port range
  • i
    Show all users whos ident (username) matches the given mask
  • M
    Show all users who have metadata attached to them with the given key name
  • l
    Show only local users
  • f
    Show only remote (far) users
You may combine multiple flags in one WHO command except where stated.
Returns the host-name and nickname of a user, and some other miscellaneous information.
