LSHW(1)

💖 LSHW(1) — lshw ✨

okay so bestie, lshw is literally the tool that lists hardware for you 💅 It's a small program that pulls out super detailed info on your machine's hardware setup. It can report exact memory config, firmware version, mainboard config, CPU version and speed, cache config, bus speed, etc. 🤓 on DMI-capable x86 or IA-64 systems, and on some PowerPC machines (PowerMac G4 is known to work 🍎).

It currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB. The whole list is giving main character energy 👑

🎀 SYNOPSIS 🎀

lshw [ -version ]

lshw [ -help ]

lshw [ -X ]

lshw [  [ -html ]  [ -short ]  [ -xml ]  [ -json ]  [ -businfo ]  ]  [
-dump filename ]  [ -class class... ]  [ -disable test... ]  [ -enable
test... ]  [ -sanitize ]  [ -numeric ]  [ -quiet ]  [ -notime ]

🦋 DESCRIPTION 🦋

Here's the vibe check for every flag, bestie 🫶

• -version — shows you the version of lshw and then exits 🌸
• -help — shows the available command line options and quits 💜
• -X — launches the X11 GUI (if it's available) ✨
• -html — outputs the device tree as an HTML page 🌈
• -xml — outputs the device tree as an XML tree 🍓
• -json — outputs the device tree as a JSON object (JavaScript Object Notation) 🧚
• -short — outputs the device tree showing hardware paths, very much like the output of HP-UX's ioscan 💅
• -businfo — outputs the device list showing bus information, detailing SCSI, USB, IDE and PCI addresses 🔥
• -dump filename — displays output and dumps collected info into a file (SQLite database) 🗂️
• -class class — only shows the given class of hardware. You can find class using lshw -short or lshw -businfo 👑
• -C class — alias for -class class 🎀
• -enable test and -disable test — enables or disables a test 🙈 The test can be:
  • dmi (for DMI/SMBIOS extensions)
  • device-tree (for OpenFirmware device tree)
  • spd (for memory Serial Presence Detect)
  • memory (for memory-size guessing heuristics)
  • cpuinfo (for kernel-reported CPU detection)
  • cpuid (for CPU detection)
  • pci (for PCI/AGP access)
  • isapnp (for ISA PnP extensions)
  • pcmcia (for PCMCIA/PCCARD)
  • ide (for IDE/ATAPI)
  • usb (for USB devices)
  • scsi (for SCSI)
  • network (for network interfaces detection)
• -quiet — don't display status 🤫
• -sanitize — removes potentially sensitive info from the output (IP addresses, serial numbers, etc.) 🔒
• -numeric — also displays numeric IDs (for PCI and USB devices) 🔢
• -notime — excludes volatile attributes (timestamps) from the output ⏰

💀 BUGS 💀

lshw currently does not detect Firewire (IEEE1394) devices. Yikes 🙈

Not all architectures supported by GNU/Linux are fully supported (e.g. CPU detection). Not every platform is on the guest list yet 😭

"Virtual" SCSI interfaces used for SCSI emulation over IDE are not reported correctly yet. 💔

🌸 NOTES 🌸

lshw must be run as super user or it will only report partial information. Bestie, sudo it 🫶

🗂️ FILES 🗂️

• /usr/local/share/pci.ids
• /usr/share/pci.ids
• /etc/pci.ids
• /usr/share/hwdata/pci.ids — a list of all known PCI IDs (vendors, devices, classes and subclasses). If compiled with zlib support, lshw will look for pci.ids.gz first, then for pci.ids. ✨
• /proc/bus/pci/* — used to access the configuration of installed PCI buses and devices 🔌
• /proc/ide/* — used to access the configuration of installed IDE buses and devices 💾
• /proc/scsi/*, /dev/sg* — used to access the configuration of installed SCSI devices 🧷
• /dev/cpu/*/cpuid — used on x86 platforms to access CPU-specific configuration 🧠
• /proc/device-tree/* — used on PowerPC platforms to access OpenFirmware configuration 🍎
• /proc/bus/usb/* — used to access the configuration of installed USB buses and devices 🔋
• /sys/* — used on 2.6 kernels to access hardware/driver configuration information 🌈

🧚 EXAMPLES 🧚

lshw -short

Lists hardware in a compact format 💖

lshw -class disk -class storage

Lists all disks and storage controllers in the system 💾

lshw -html -class network

Lists all network interfaces in HTML 🌐

lshw -disable dmi

Don't use DMI to detect hardware 🙈
