I have a text file -- say temp.txt -in the format--

name1@url1@text1
name1@url1@text1
name1@url1@text2
name2@url2@text2
name3@url3@text3
name4@url4@text4, etc

I need to remove the duplicate files - say line 1 and line 2, and also remove line 3 since it has the same url1 as line 1hence the file that is required now is ---

name1@url1@text1
name2@url2@text2
name3@url3@text3
name4@url4@text4, etc
any assistance shall be appreciated..
