lsdev

lsdev: list the devices on the bus.

Synopsis

lsdev [-i]

Description

lsdev lists the devices on the computer’s bus, as a table with a header row:

NAME: The kernel’s name for it: its type and its place among devices of that type in bus order (terminal0, storage1). Every device has a file by that name in /dev, whose ioctls are its methods.
TYPE: What kind of device it is.
PATH: Its slot address, as sata:0 or exp:2; - for a device that is not in a slot (a cabled screen, a card in a hub).
ID: Its id address, id:uuid, which names it however it is connected. Shown only with -i.
LABEL: The name the player gave its item, if any.

Rows are in bus order. The list is the kernel’s: it reads the bus when the bus says it changed (or a device it called is gone), so just after a change it may be a moment behind.

Options

-i: Add the ID column.

Exit status

0 on success; 1 on any other argument.

Notes

Bus positions (the numbers in the case view) are not addresses; programs name devices by their path or id.
