kudzu Command in Linux
The kudzu command is a hardware detection tool used in Linux systems, particularly in Red Hat-based distributions like Fedora and CentOS. It is designed to detect and configure new and existing hardware components in the system.
The kudzu command can probe the system for hardware changes, configure newly detected devices, and update existing configurations. This tool is particularly useful for system administrators and users who need to manage hardware components on their Linux systems.

Syntax of kudzu Command
The basic syntax for the kudzu command is as follows −
kudzu [options]
The command can be executed with various options to perform different operations, such as probing for new hardware, configuring detected devices, and updating existing configurations.
kudzu Command Options
Let's understand some of the options commonly used with the kudzu command along with their descriptions −
-p or --probe
This option is used to probe the system for new or changed hardware. The kudzu command will detect any new hardware components and prompt the user to configure them. For example −
sudo kudzu -p
In this example, the -p option tells kudzu to probe the system for new hardware. If any new hardware is detected, the user will be prompted to configure it.
-s or --safe
This option is used to run kudzu in safe mode, which prevents any changes from being made to the system configuration. It is useful for testing hardware detection without making any changes. For example −
sudo kudzu -s
In this example, the -s option tells kudzu to run in safe mode, detecting hardware without making any changes to the system configuration.
-b or --bus
This option is used to specify a particular bus type for hardware detection. The kudzu command will only probe for hardware on the specified bus. For example −
sudo kudzu -b pci
In this example, the -b option specifies the PCI bus for hardware detection. The kudzu command will only probe for hardware components on the PCI bus.
-c or --class
This option is used to specify a particular class of hardware for detection. The kudzu command will only probe for hardware in the specified class. For example −
sudo kudzu -c network
In this example, the -c option specifies the network class for hardware detection. The kudzu command will only probe for network hardware components.
-f or --file
This option is used to specify a configuration file for kudzu to use. The specified file will be used for hardware detection and configuration. For example −
sudo kudzu -f /etc/kudzu.conf
In this example, the -f option specifies the /etc/kudzu.conf configuration file for kudzu to use during hardware detection and configuration.
-h or --help
This option displays the help message, providing a summary of the available options and their usage. For example −
kudzu -h
Detecting and Configuring New Hardware
One of the primary uses of the kudzu command is to detect and configure new hardware components on a Linux system. When new hardware is added to the system, such as a new network card or storage device, the kudzu command can be used to detect the new hardware and prompt the user to configure it.
For example −
sudo kudzu -p
In this example, the -p option tells kudzu to probe the system for new hardware. If any new hardware is detected, the user will be prompted to configure it. The kudzu command will guide the user through the configuration process, ensuring that the new hardware is properly set up and ready for use.
How to Use the kudzu Command in Linux?
The kudzu command can be run in safe mode to test hardware detection without making any changes to the system configuration. This is useful for verifying that the kudzu command correctly detects hardware components without modifying the existing configuration.
Example −
sudo kudzu -s
In this example, the -s option tells kudzu to run in safe mode. The kudzu command will detect hardware components but will not make any changes to the system configuration. This allows the user to verify hardware detection without affecting the current setup.
Specifying a Particular Bus for Detection
The kudzu command can be used to probe for hardware components on a specific bus type. This is useful for situations where the user wants to focus on detecting hardware components on a particular bus, such as PCI, USB, or ISA.
Example −
sudo kudzu -b usb
In this example, the -b option specifies the USB bus for hardware detection. The kudzu command will only probe for hardware components on the USB bus.
Specifying a Particular Class of Hardware
The kudzu command can be used to probe for hardware components in a specific class. This is useful for situations where the user wants to focus on detecting a particular type of hardware, such as network devices, storage devices, or input devices.
Example −
sudo kudzu -c storage
In this example, the -c option specifies the storage class for hardware detection. The kudzu command will only probe for storage hardware components.
Using a Configuration File
The kudzu command can use a specified configuration file for hardware detection and configuration. This allows the user to provide custom settings and preferences for the hardware detection process.
Example −
sudo kudzu -f /etc/kudzu.conf
In this example, the -f option specifies the /etc/kudzu_custom.conf configuration file for kudzu to use during hardware detection and configuration. The kudzu command will read the settings from the specified file and apply them during the detection process.
Examples of kudzu Command in Linux
Let's explore some practical examples to demonstrate the use of the kudzu command in different scenarios.
- Detecting New Network Hardware
- Detecting and Configuring USB Devices
Detecting New Network Hardware
When a new network card is added to the system, the kudzu command can be used to detect and configure the new hardware. For example −
sudo kudzu -c network -p
In this example, the -c option specifies the network class for hardware detection, and the -p option tells kudzu to probe the system for new network hardware. The kudzu command will detect the new network card and prompt the user to configure it.
Detecting and Configuring USB Devices
The kudzu command can be used to detect and configure new USB devices added to the system. For example −
sudo kudzu -b usb -p
In this example, the -b option specifies the USB bus for hardware detection, and the -p option tells kudzu to probe the system for new USB hardware. The kudzu command will detect the new USB devices and prompt the user to configure them.
Conclusion
The kudzu command is primarily used for hardware detection and configuration in Red Hat-based distributions. If you're using a different Linux distribution, kudzu may not be available or may behave differently. Make sure you have the necessary permissions to run the kudzu command, and you may need to use sudo to run it with elevated privileges.
