Recently I have begun to use with Linux. Well it’s a great operating system. If there 10 lines in the files how will I print the unique line from that file. I don’t require to similar line on the screen. I am here because many of you are familiar with the Linux. I thought I will definitely get solution from you. If you have any suggestion please let me know. I will be really thankful to you. Please tell me appropriate solution as soon as possible.
