.SH DESCRIPTION
\fBliquidctl\fR is a utility for overseeing and controlling some hardware
monitoring devices not yet supported at the kernel level.
.if !\n[is_macos]\{  Because \fBliquidctl\fR directly accesses the hardware devices, root
privileges are generally required, though this can be avoided with
appropriate udev rules.
.\}
.PP
\fBliquidctl list\fR outputs all compatible devices found on the system.  In
case more than one device is found, the desired one can be selected for later
invocations with \fB--match=\fIsubstring\fR, where \fIsubstring\fR matches part
of the desired device's description using a case insensitive comparison.
.PP
\fBliquidctl list \fI\-\-verbose\fR enables the display of additional
identifiers and addresses that can also be used to select specific devices.
These can be better suited for certain use cases, such as non-interactive
scripts.
.PP
\fBliquidctl initialize\fR prepares a device for later commands, and most
devices must be initialized after every boot or when resuming from a suspended
state.  Unless finer control is required, all devices can be initialized at
once with \fBliquidctl initialize all\fR.  Some devices may output some
information at this stage.
.PP
\fBliquidctl status\fR displays the status of all devices that match the
provided filtering options.
.PP
\fBliquidctl set \fIchannel\fB speed\fR allows the user to set fan and pump
speeds.  These, depending on the device, can be set to fixed duty values,
variable temperature\–duty curves, or both.
.PP
\fBliquidctl set \fIchannel\fB color\fR allows the user to configure and set
lighting modes.  Supported lighting modes and additional options vary by device
and are listed in later sections of this manual.  Each color can be specified
as:
.IP \(bu
hexadecimal RGB with or without prefix '0x': \fIff7f3f\fR;
.IP \(bu
decimal RGB triple, R,G,B ∊ [0, 255]: \fIrgb(255,127,63)\fR;
.IP \(bu
hue\-saturation\-value HSV triple, H ∊ [0, 360], S,V ∊ [0, 100]: \fIhsv(20,75,100)\fR;
.IP \(bu
hue\-saturation\-lightness HSL triple, H ∊ [0, 360], S,L ∊ [0, 100]: \fIhsl(20,100,62)\fR.
.
