+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
+

+
+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).
+
