I was trying to install mysql in centOS, which is rpm based Linux operating system like redhat, fedora etc. And I wanted to find out if it already installed or not.

Many times I forget the Linux command which is used to see the centOS linux operating system version. So, decided to write down it here on my blog and refer back when i forget. I hope it may also help others!

What is NFS and NFS service NFS is the network file system, which is used to mount or link the file system or simply folders from one linux machine to another linux machine. This mounting makes folders and files transparently available  to the other linux machines across the network.

NFS stands for Network File System. And this is the one which is most widely used file system on Linux operating system based computers. Using this file system you can actually mount a file(s) from one Linux computer to another Linux computer if the both system are in the same network(LAN).
