It + controls the runtime behavior of udev, requests kernel events, + manages the event queue, and provides simple debugging mechanisms. + + + OPTIONS + + udevadm info <replaceable>options</replaceable> + Queries the udev database for device information + stored in the udev database. It can also query the properties + of a device from its sysfs representation to help creating udev + rules that match this device. + + + + + Query the database for specified type of device data. It needs the + or to identify the specified + device. Valid queries are: + name, symlink, path, + env, all. + + + + + + The devpath of the device to query. + + + + + + The name of the device node or a symlink to query + + + + + + The udev root directory: /dev. If used in conjunction + with a name or symlink query, the + query returns the absolute path including the root directory. + + + + + + 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. + + + + + + Print major/minor numbers of the underlying device, where the file + lives on. + + + + + + Export the content of the udev database. + + + + + + Print version. + + + + + + Print help text. + + + + + + udevadm trigger <optional>options</optional> + Request device uevents, usually used to replay events at system coldplug. + + + + + Print the list of devices which will be triggered. + + + + + + Do not actually trigger the event. + + + + + + Trigger only the events which are failed during a previous run. + + + + + + Type of event to be triggered. The default value is "add". + + + + + + Trigger events for devices which belong to a matching subsystem. This option + can be specified multiple times and supports shell style pattern matching. + + + + + + Do not trigger events for devices which belong to a matching subsystem. This option + can be specified multiple times and supports shell style pattern matching. + + + + + + Trigger events for devices with a matching sysfs attribute. If a value is specified + along with the attribute name, the content of the attribute is matched against the given + value using shell style pattern matching. If no value is specified, the existence of the + sysfs attribute is checked. This option can be specified multiple times. + + + + + + Do not trigger events for devices with a matching sysfs attribute. If a value is + specified along with the attribute name, the content of the attribute is matched against + the given value using shell style pattern matching. If no value is specified, the existence + of the sysfs attribute is checked. This option can be specified multiple times. + + + + + + Pass the synthesized events to the specified socket, instead of triggering + a global kernel event. All available event values will be send in the same format + the kernel sends an uevent, or + sends a message. If the first character of the specified path is an @ character, + an abstract namespace socket is used, instead of an existing socket file. + + + + + + Pass an additional environemt key to the event. This works only with the + --socket option. + + + + + + udevadm settle <optional>options</optional> + Watches the udev event queue, and exits if all current events are handled. + + + + + Maximum number of seconds to wait for the event queue to become empty. + The default value is 180 seconds. + + + + + + Print help text. + + + + + + udevadm control <replaceable>command</replaceable> + Modify the internal state of the running udev daemon. + + + + + Set the internal log level of udevd. Valid values are the numerical + syslog priorities or their textual representations: , + and . + + + + + + Signal udevd to stop executing new events. Incoming events + will be queued. + + + + + + Signal udevd to enable the execution of events. + + + + + + Signal udevd to reload the rules from the config. + + + + + + Set global variable. + + + + value + + Set the maximum number of events, udevd will handle at the + same time. + + + + + + Set the maximum number of events, which are allowed to run at the + same time. + + + + + + Print help text. + + + + + + udevadm monitor <optional>options</optional> + Listens to the kernel uevents and events sent out by a udev rule + and prints the devpath of the event to the console. It can be used to analyze the + event timing, by comparing the timestamps of the kernel uevent and the udev event. + + + + + + Print the complete environment for all events. Can be used to compare the + kernel supplied and the udev added environment values. + + + + + + Print the kernel uevents. + + + + + + Print the udev event after the rule processing. + + + + + + Print help text. + + + + + + udevadm test <optional>options</optional> <replaceable>devpath</replaceable> + Simulate a udev event run for the given device, and print out debug + output. Unless forced to, no device node or symlink will be created. + + + + + The action string. + + + + + + The subsystem string. + + + + + + Force the creation of a device node or symlink. Usually the test run + prints only debug output. + + + + + + Print help text. + + + + + + udevadm version + Print version number. + + + udevadm help + Print help text. + + + + AUTHOR + Written by Kay Sievers kay.sievers@vrfy.org. + + + + SEE ALSO + + udev7 + + + udevd8 + + + +
