Exclude the repeats

Hi to all..
I am new to linux
I want to remove the repeats of patterns in my file.
My file is like this

master1
master2
shisya2
shisya3
guru7
guru9

As u find we have master, shisya and guru as 3 names...I want to delete the occurances of master/shisya/guru more than one time in the order of the original file..

The O/P must be

master1
shisya2
guru7

Kindly help........

He probably wants you to try your hands on this and then come with errors.
