Overview

The command hwinfo prints information about your hardware:

• CPU
• block devices aka hard disk, CD ROM, floppy
• BIOS
• network card

hwinfo should be installed by default. However if it is not find out your distribution to find out how to install it:

• for SUSE:

yast -i hwinfo

• for Debian, Raspbian, Ubuntu, Kubuntu, Flubuntu, Xubuntu, GEUbuntu, Edubuntu, ...:

apt-get install hwinfo

• for Fedora, Red Hat, Red Flag, Asianux, ...:

yum install hwinfo

Run it

To print information about your hardware:

# hwinfo --help

  --short        just a short listing
  --log logfile  write info to logfile
  --debug level  set debuglevel
  --version      show libhd version
  --dump-db n    dump hardware data base, 0: external, 1: internal
