Need help in grep

hi all,

I would like to grep without duplication, what should I do,

say

I have file abc.txt

contains
Code:
n xyz jik
n xyz jik

I have another file def.txt

what command I should use in script to copy n xyz jik once from abc.txt to def.txt

right now I am using

Code:
grep -i "xyz" $abc >>$def

but it causes duplication

and thus the output is
Code:
n xyz jik
n xyz jik

I want it to be

Code:
n xyz jik

looking forward for the reply

Thank you in advanceSmilie
