.SH "DESCRIPTION"
.PP
udevinfo queries the udev database for device information stored in the udev database. udevinfo also queries the properties of a device from its sysfs representation to help creating udev rules to match this device.
.SH "OPTIONS"
.TP
\fB\-q\fR
Query the database for specified type of device data. It needs the 
\fB\-p\fR 
or 
\fB\-n\fR 
to identify the specified device. Valid queries are: 
\fBname\fR, 
\fBsymlink\fR, 
\fBpath\fR, 
\fBenv\fR, 
\fBall\fR.
.TP
\fB\-a\fR
Print all sysfs properties of the specified device that can be used in udev rules to match the specified device. It prints all devices along the chain, up to the root of sysfs that can be used in udev rules.
.TP
\fB\-p \fR\fB\fIdevice\-path\fR\fR
The sysfs path of the device to query.
.TP
\fB\-n \fR\fB\fInode\-name\fR\fR
The name of the device node or a symlink to query
.TP
\fB\-r\fR
The udev root directory: 
\fI/dev\fR. If used in conjunction with a 
\fBname\fR 
or 
\fBsymlink\fR 
query, the query returns the absolute path.
.TP
\fB\-e\fR
Export the content of the udev database.
.TP
\fB\-h\fR
Print help text.
