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.
|

|
|
|
|

|
|

|
|
|
|
Using lshw will show you all the Hardware information on your screen.
|
|
|

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
|
|
|
|
