It can report exact memory configuration, firmware version, mainboard configuration,\nCPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 sys‐\ntems and on some PowerPC machines (PowerMac G4 is known to work).\n\n## TLDR\n\n> List detailed information about hardware configurations as root user.\n\n- Launch the X11 GUI (if available):\n `sudo lshw -X`\n- List all hardware in tabular format:\n `sudo lshw -short`\n- List multiple class of hardware (all disks and storage controllers) in tabular format:\n `sudo lshw {{-c|-class}} disk {{-c|-class}} storage -short`\n- Save all network interfaces to an HTML/XML/JSON file:\n `sudo lshw {{-c|-class}} network -{{html|xml|json}} > interfaces{{.html|.xml|.json}}`\n- List network interfaces without revealing sensitive information (IP addresses, serial numbers, etc.):\n `sudo lshw {{-c|-class}} network -sanitize`\n- List a particular class of hardware:\n `sudo lshw {{-c|-class}} {{system|bridge|memory|processor|address|storage|disk|tape|bus|network|display|input|printer|multimedia|communication|power|volume|generic}}`\n\n*Source: tldr-pages*\n\n## Sections\n\n- **NAME**\n-
