# lsfirewirephy(8)

list PHYs of FireWire devices

## NAME

lsfirewirephy - list PHYs of FireWire devices

## SYNOPSIS

**lsfirewirephy** \[*options*\] \[*devicenode* \[*phyid*\]\]

## DESCRIPTION

The **lsfirewirephy** utility prints the device IDs of the PHYs of one or more FireWire devices.

The *devicenode* parameter specifies the device file (*/dev/fw*\*) of the device whose PHY ID you want to print.

The *phyid* parameter specifies the node number of the device; in this case, *devicenode* identifies the bus and must be a local node. The node number is zero-based and cannot be larger than 62. Use this to address a single device that does not have a */dev/fw*\* file, such as a repeater, a powered-down device, or a VersaPHY device.

Without any parameters, **lsfirewirephy** prints the PHY IDs of all devices on all buses.

## OPTIONS

- **--help**

  Print a summary of the command-line options and exit.

- **--version**

  Print the version number of **lsfirewirephy** on the standard output and exit.
