How do I get detailed hardware information about my Linux server using command line options? What is the Linux command to find out hardware information?
You can use any one of the following tool to extract detailed information on the hardware configuration of the machine:
- dmidecode command – See a description of the system’s hardware components, as well as other useful pieces of information such as serial numbers and BIOS revision.
- lshw command – list hardware command.
- ls* commands.
- /proc/ file system
Method #1 dmidecode tool
Use yum or apt-get command to install dmidecode tool. Once installed, type the following command to list hardware information:
# dmidecode
Sample outputs:
SMBIOS 2.6 present.
18 structures occupying 992 bytes.
Table at 0x0009B400.
Handle 0x0000, DMI type 0, 24 bytes

System Information
Manufacturer: ICP / iEi
Product Name: TS-859 PRO
Version: V1.0
Serial Number: To Be Filled By O.E.M.
See our article “Get Information About Your BIOS / Server Hardware From a Shell Without Opening Chassis” for more information.
Method #2: lshw too
This tool an report exact memory configuration, firmware version, main board configuration, CPU version and speed, cache configuration, bus speed, etc. on DMI-capable x86 or IA-64 systems and on some PowerPC machines. 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.
NOTE: Install lshw either using ‘apt-get install lshw‘ (Debian and Friends) or ‘yum instal lshw‘ (Red Hat and Friends). YMMV.
List hardware
Type the lshw at a shell prompt:
# lshw | more
OR
# lshw
Sample outputs:

ls* Commands
Use the lspci command list all PCI devices on Linux based systems:
# lspci
Use the lscpu command to display information on CPU architecture using Linux based systems:
# lscpu
Use the lsusb command to display information on USB devices using Linux based systems:
# lsusb
Use lsscsi command to list SCSI devices (or hosts) and their attributes on Linux:
