This is working fine. But this will replace the 'N' present in other rows also.

my file contains
xxx xxx1 N N N 0
yyy yyy1 Y N N 0

i want output as xxx xxx1 Y N N 0
yyy yyy1 Y N N 0
i want to replace N from one particular row at a time.
i did like this
grep xxx file | sed 's/N/Y/1'
this will change xxx xxx1 Y N N 0 but i want yyy yyy1 Y N N 0 row also.
what changes i need to do?
