Can anyone work Linux? I need help, please!?

What are the steps?
•Task 1: Configure and access an NFS share.
Procedure
1. Boot from the Live CD and log on to the system.
2. Go to Applications> System Tools> Terminal.
3. Gain root user privileges with the su – command.
4. Use vi to edit the file /etc/exports with the command vi /etc/exports. The file should be empty.
5. Add the line /home/share *(ro) to share a directory called share to every client with read-only permissions. Save and exit vi.
6. Make the directory /home/share with the command mkdir /home/share.
7. Use the command ps aux > /home/share/data.txt to use the output of the ps command to create a file called data.txt in your new share directory.
8. Start the NFS service with the command service nfs start.
9. Use the command exportfs –a to enable the share:
10. Create a directory called shared in /root with the command mkdir /root/shared.
11. Connect to the NFS share with the command mount –t nfs localhost:/home/share /root/shared. This will access the NFS share in the same way Linux might access a Universal Serial Bus (USB) drive. The NFS directory structure will now be under the /root/shared directory.
12. Use the command df –h to list the filesystems currently being accessed. Record the output of this command for your lab report.
Note: The line that has localhost:/home/share is on the far left of the line and /root/shared is on the far right of the same line.

13. Verify that you have accessed the share by comparing the output of ls –l /root/shared/data.txt to the output of ls –l /home/share/data.txt:
14. Use the command showmount –a localhost to list the NFS shares on your PC. Record the output of this command for your lab report.
Note: Localhost is the nickname of the PC and uses the local loopback 127.0.0.1.
15. To stop accessing that share, use the command umount /root/share:
16. Stop the NFS service with the command service nfs stop. The lab is now complete.
17. Log off Fedora and reboot the PC normally.
