+Commands to check System & Hardware Information
+======
+Hello linux-fanatics, in this post i will be discussing some important that will make your life as System Administrator. As we all know being a good System Administrator means knowing everything about your IT Infrastructure & having all the information about your servers, whether its hardware or OS. So following commands will help you out in extracting out all the hardware & system information.
+
+#### 1- Viewing system information
+
+$ uname -a
+
+![uname command][2]
+
+It will provide you all the information about your system. It will provide you with Kernel name of system, Hostname, Kernel version, Kernel Release, Hardware name.
+
+#### 2- Viewing Hardware information
+
+$ lshw
+
+![lshw command][4]
+
+Using lshw will show you all the Hardware information on your screen.
+
+#### 3- Viewing Block Devices(Hard disks, Flash drives) information
+
+$ lsblk
+
+![lsblk command][6]
+
+lsblk command prints all the information regarding block devices on screen. Use lsblk -a to show all the block devices.
+
+#### 4- Viewing CPU information
+
+$ lscpu
+
+![lscpu command][8]
+
+lscpu shows all the CPU information on screen.
+
+#### 5- Viewing PCI information
+
+$ lspci
+
+![lspci command][10]
+
+All the network adapter cards, USB cards, Graphics cards are termed as PCIs. To view their information use lspci .
+
+lspci -v will give detailed information regarding PCI cards.
+
+lspci -t will show them in tree format.
+
+#### 6- Viewing USB information
+
+$ lsusb

+
+#### 7- Viewing SCSI information
+
+$ lssci
+
+![lssci][14]
+
+To view SCSI information type lsscsi. lsscsi -s will also show the size of partition.
+
+#### 8- Viewing file system information
+
+$ fdisk -l
+
+![fdisk command][16]
+
+Using fdisk -l will show information regarding the file system. Although main function of fdisk utility is to modify a file system, you can create new partitions, delete old ones ( more on that in my future tutorial).
+
+That's it for now my fellow Linux-fanatics . You are advised to check out my other posts regarding Linux commands **[HERE][17] & ** another one **[HERE][18]
