Hi Guys...

Please Could you help me with the following ?

aaaa bbbb cccc sdsd
aaaa bbbb cccc qwer

as you can see, the 2 lines are matched in three fields...
how can I delete this pupicate ? I mean to delete the second one if 3 fields were duplicated ?

Thanks

i) Use useful topics!
ii)

awk -F" " '! something[$3]++' inputfile

Could you explain this command for me ....

and what do u mean by " Use useful topics "...

Regards

You've named this thread - your question - simply "help". It would be much better to use something like "removing duplicate lines".

And well, I see you've finally used the board search finding duplicates in columns and removing lines .

Let's put it together:
i) you've used a meaningless topic
ii) you've posted your problem three times
iii) you've already found a thread in which you problem is answered and explained

Do you really believe this will motivate me to explain this to you? I don't.

Dear fabtagon.....

I posted this topic in 3 different places to make sure that my problem can be handled by someone who can deal well enough with Unix.. and as I expected, someone came, like you, and gave a solution that makes no sense at all... thats why I had to post it in different places.. GOT IT !!

Please if you have a stright answer... be my guest, otherwise... go and practice som unix commands.....
Cappich ???

Warm regards Bozo
