Check Hardware and System Information in Linux10 Instructions to Test {Hardware} and System Data in Linux

Due to this fact in the following tips and methods sequence, we will have a look at some helpful instructions that may make it easier to to extract details about your Linux system and {hardware} parts.

1. How one can View Linux System Data

To know solely the system title, you need to use the uname command with none swap that can print system info or the uname -s command will print the kernel title of your system.

[email protected] ~ $ uname

Linux

To view your community hostname, use the ‘-n’ swap with the uname command as proven.

[email protected] ~ $ uname -n

tecmint.com

To get details about kernel-version, use the ‘-v’ swap.

[email protected] ~ $ uname -v

#64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014

To get the details about your kernel launch, use the ‘-r’ swap.

[email protected] ~ $ uname -r

3.13.0-37-generic

To print your machine {hardware} title, use the ‘-m’ swap:

[email protected] ~ $ uname -m

x86_64

All this info may be printed without delay by working the ‘uname -a’ command as proven under.

[email protected] ~ $ uname -a

Linux tecmint.com 3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2. How one can View Linux System {Hardware} Data

Right here you need to use the lshw instrument to collect huge details about your {hardware} parts comparable to cpu, disks, reminiscence, usb controllers, and so forth.

lshw is a comparatively small instrument and there are few choices that you need to use with it whereas extracting info. The knowledge supplied by lshw was gathered from totally different /proc recordsdata.

Word: Do keep in mind that the lshw command is executed by the superuser (root) or sudo person.

Learn Additionally: Distinction Between su and sudo Person in Linux

To print details about your Linux system {hardware}, run this command.

7. How one can Print SCSI Units Data

To view all of your scsi/sata units, use the lsscsi command as follows. Should you should not have the lsscsi instrument put in, run the next command to put in it.

$ sudo apt-get set up lsscsi [on Debian derivatives]
# yum set up lsscsi [On RedHat based systems]
# dnf set up lsscsi [On Fedora 21+ Onwards]

After set up, run the lsscsi command as proven:

[email protected] ~ $ lsscsi

[0:0:0:0] disk ATA ST1000LM024 HN-M 2BA3 /dev/sda
[1:0:0:0] cd/dvd PLDS DVD-RW DA8A5SH RL61 /dev/sr0

8. How one can Print Details about SATA Units

You’ll find some details about sata units in your system as follows utilizing the hdparm utility. Within the instance under, I used the block system /dev/sda1 which is the arduous disk on my system.

[email protected] ~ $ sudo hdparm /dev/sda1

/dev/sda1:
multcount = 0 (off)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 56065/255/63, sectors = 2048000, begin = 2048

To print details about system geometry when it comes to cylinders, heads, sectors, dimension, and the beginning offset of the system, use the -g possibility.

[email protected] ~ $ sudo hdparm -g /dev/sda1

/dev/sda1:
geometry = 56065/255/63, sectors = 2048000, begin = 2048

9. How one can Test Linux File System Data

To collect details about file system partitions, you need to use the fdisk command. Though the primary performance of the fdisk command is to change file system partitions, it will also be used to view details about the totally different partitions in your file system.

You’ll be able to print partition info as follows. Bear in mind to run the command as a superuser or else it’s possible you’ll not see any output.

[email protected] ~ $ sudo fdisk -l

WARNING: GPT (GUID Partition Desk) detected on ‘/dev/sda’!
The util fdisk would not assist GPT. Use GNU Parted.

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
