- To find the serial number of the computer, open a terminal window and install dmidecode using apt-get as below:$ sudo apt-get install dmidecode Thereafter, enter the following command to get the serial number:$ sudo dmidecode grep -i serial Now you will see the serial number of the computer.
- Use the command DSPSYSVAL and press F4 to prompt it. For the model number, the System Value parameter is QMODEL. For the serial number, the System Value Parameter is QSRLNBR. For the processor code, the System Value Parameter is QPRCFEAT.
- If you want to get a serial number of the system in any Linux system like Ubuntu, run following command in terminal. Sudo dmidecode -s system-serial-number This will highlight the serial number of the hardware. You can also use the dmidecode to read any specific hardware/system parameter by specifying the parameter name.
- In most cases 'system-serial-number' is like either 'chassis-serial-number' or 'baseboard-serial-number'. Remember that not all distros have this program installed, for instance, Debian based systems have a package named after it. Otherwise you can find a unique and persistent, thro' installs, system ID via your system's disk; to do that you.
For Windows: If you are using Windows, you can check serial number and all other hardware related information in system property using User Interface. You can also get system info using system information command in windows.
It isn’t again a difficult task to find the service tag number for Dell and other laptops on Linux, as well. You might need superuser or administrator privileges for this command though. Open ‘ Terminal ’, and type ‘ sudo dmidecode -s system-serial-number ’, and hit the enter key.

For Linux: If you are using any of the Linux systems, you have to run the command to the system details like serial number, manufacturing model… You can do this easily by the dmidecode command in the command line terminal.
What is the dmidecode command?
It is a command to read DMI table. The name itself depicts as it is a command to decode the value in DMI table.
What is DMI Table in Linux?
DMI table is also called as SMBIO. This table consists of all the hardware, processor, system, BIOS information, etc.
Role of dmidecode Command:
A dmidecode command just fetches the content from this table and display it in the human-readable format on the terminal.
Run this command.
If it is not working, it requires root permission. Try getting admin privilege by running following sudo command.
It will give a long list of information. To shorten it or to get the particular information you have to be specific.
How to check the Manufacturer, Model, and Serial Number?
Run the following command.
This command will give complete information about the system.
How to get serial number in Linux?
If you want to get a serial number of the system in any Linux system like Ubuntu, run following command in terminal.
This will highlight the serial number of the hardware.
You can also use the dmidecode to read any specific hardware/system parameter by specifying the parameter name.
Note: Kindly make a note. While running any of the dmidecode commands, try all these commands running without sudo first. If you get any error or system ask you for any privilege, use the commands with sudo.
I have tested and verified all these commands on Ubuntu Linux machine. If you are using any other Linux OS system, kindly check, How to get serial number in Linux using the same commands. Do share your result. It will be helpful for other candidates.

How to identify a device > serial device
How to 'identify' the serial device (/dev/ttyS*) for a given interface of your computer (not the peripheral connected behind it).
The serial interfaces (RS-232) is a legacy interface. It has no enumeration process, you have to tell your application which /dev/ttyS* to use (some application do have some auto-detection features, but it's not always reliable). Swat 4 the stetchkov syndicate original exergen.
The Serial port can either have a physical interface on your computer:
- DB9 serial interface.
- DB25 serial interface (on older computers).
- RJ-45 serial interface (mostly on switch and routers, but also on some computers like Sun ones).
Or it can be 'built-in' another device, like:
- Internal Modem (ISA, PCI..).
- PC Card (pcmcia, Cardbus..), including Modem, GSM or UMTS/3G cards.
- USB to serial adapters.
- Docking station (for laptop).
Often, the computer have an internal UART chipset, but not a physical interface : Recent laptops have the DB-9 connector on the docking station only ; Some desktop have 1 connector available, the 2nd requires an optional cable, etc. so what you see IS NOT what you have.
Using hal
hal in installed by default in Desktop Environment (both Gnome and Kde), but not on servers.
Take special attention to 'info.product' and 'linux.device_file' lines :

Find in /sys/*
This command should work on all standard Debian installation (even minimalist ones).
some explanations on this example :
if you look at the lspci output above, pci device '00:1e.0' is a PCI bridge to the card bus controller ('15:00.0'), so ttyS1 is a PC Card device.
if you look at the lspci output above, pci device '00:1a.0' is a USB Controller, so ttyUSB1 is a USB device (USB-to-serial or modem).
