SYNOPSIS
lshw [ options ]
PARAMETERS
-help
Displays a help message with available options.-version
Shows the version of lshw
.-format format
Specifies the output format. Supported formats include html
, xml
, json
, and short
(default is plain text).-class class
Limits the output to a specific hardware class (e.g., network
, disk
, memory
). See output of the `lshw` command for all possible classes-C class
Same as -class class
.-businfo
Displays bus information (e.g., PCI slot, USB port) for each device.-numeric
Displays numeric IDs instead of human-readable descriptions.-quiet
Reduces the amount of output. Useful for automated scripting.-sanitize
Masks potentially sensitive information (e.g., serial numbers) in the output.-enable capability
Enables a specific capability during hardware detection.
Examples are: 'pci', 'dmi', 'usb', 'memory', 'cpu', 'scsi', 'ide', 'network', 'bios', 'floppy', 'cdrom', 'partition', 'volume', 'power', 'bridge', 'system', 'mainboard', 'display', 'multimedia', 'printer', 'camera', 'input', 'storage', 'bus', 'generic'-disable capability
Disables a specific capability during hardware detection.
Examples are: 'pci', 'dmi', 'usb', 'memory', 'cpu', 'scsi', 'ide', 'network', 'bios', 'floppy', 'cdrom', 'partition', 'volume', 'power', 'bridge', 'system', 'mainboard', 'display', 'multimedia', 'printer', 'camera', 'input', 'storage', 'bus', 'generic'-notty
Disables the use of terminal control codes for formatting.-dump
Dumps raw hardware information, which may be useful for debugging.-html
Equivalent to -format html
.-xml
Equivalent to -format xml
.-json
Equivalent to -format json
.
DESCRIPTION
lshw
(List Hardware) is a command-line utility that gathers detailed information about the hardware components of a Linux system. It scans the system's hardware and reports on devices such as the CPU, memory, disk drives, network interfaces, graphics cards, and various bus controllers. lshw
can generate output in various formats, including plain text, XML, and HTML, making it suitable for both human readability and automated processing. It doesn't directly interact with the hardware to modify its configuration, it only reads the data. The information presented by lshw
is useful for system administrators, developers, and end-users who need a comprehensive overview of the system's hardware configuration. It is particularly useful when troubleshooting hardware problems, verifying driver compatibility, or documenting system specifications. The utility aims to provide detailed output without requiring extensive knowledge of the underlying hardware.
CAVEATS
The accuracy of the information provided by lshw
depends on the completeness and accuracy of the system's hardware description. Certain virtualized environments or systems with poorly configured hardware may not provide accurate information. Root privileges may be needed to obtain information about all hardware components.
EXIT STATUS
lshw
returns 0 on success and a non-zero value on failure. A failure usually indicates problems accessing hardware information, such as insufficient permissions or errors during hardware probing.
EXAMPLES
To list all hardware information in HTML format: lshw -html > hardware.html
To list only network devices: lshw -class network
To display CPU information with bus details: lshw -class processor -businfo
HISTORY
The lshw
utility was developed to provide a standardized way to access hardware information across different Linux distributions. It has been actively maintained and updated to support new hardware devices and features. The goal was to create a tool that is both comprehensive and easy to use, abstracting away the complexities of accessing hardware information directly from the kernel.
