In C# using Management namespace, I was able to obtain all the following: Will it be possible to obtain the same In Linux via Python?,Thanks for contributing an answer to Stack Overflow!,Figured it out, by using the following we can obtain all data that I need:, Can nuclear intercontinental missiles be launched into space to destroy asteroids menacing Earth?

Figured it out, by using the following we can obtain all data that I need:

import dmidecode

def getBIOS():
   for v in dmidecode.bios().values():
   if type(v) == dict and v['dmi_type'] == 0:
   BIOSdict["Name"] = str((v['data']['Vendor']))
BIOSdict["BuildNumber"] = str((v['data']['Version']))
BIOSdict["SoftwareElementID"] = str((v['data']['BIOS Revision']))

This is a python library for inspecting hardware and devices by parsing the outputs of system utilities such as lspci and dmidecode.,In that, some of the utilities are display detailed information about all the hardware components and reset will shows only specific device information.,In this series, today we are going to discuss about python-hwinfo, it is one of the tool that display summary of hardware information and it’s configuration in the neat way.,Execute the following command to inspect the hardware present on a local machine. The output is much clear and neat which I didn’t see in any other commands.

$ sudo apt install python - pip

With all these commands, you can reduce verbiage and narrow any answer down to a single detail by parsing the command output with the grep command. For example, to view only the CPU make and model:,You can learn everything about your CPU through line commands. View CPU details by issuing either the lscpu command or its close relative lshw:,Linux command line tutorials,10 command-line tools for data analysis in Linux

Many line commands for detecting hardware must be issued under root authority. So either switch to the root user ID, or issue the command under your regular user ID preceded by sudo:

sudo <the_line_command>

In this article we’ll see how we can use Dmidecode command to retrieve hardware information of any Linux system. Suppose if we want to upgrade a system we need to gather information like Memory, BIOS and CPU etc. With help of Dmidecode command we will come to know the details without opening system chasis. Dmidecode command works for RHEL/CentOS/Fedora/Ubuntu Linux.,10 Commands to Collect System and Hardware Info in Linux,To get the information about Manufacturer, Model and Serial Number of system, use the following command as shown below.,DMI Id give us particular hardware information of system. Dmidecode with options ‘-t ‘or ‘–type‘ and ‘Id‘ will provide us the exact infromation. Id 6 will give us Memory Module information.

Below is the Demidecode command sample output.

# dmidecode 2.11
SMBIOS version fixup(2.31 - > 2.3).
SMBIOS 2.3 present.
45 structures occupying 1642 bytes.
