Thanks Thierry, Still would like a solution using a one-line sed. Will post if I find a solution.
Cheers!


Hi,

try this below. this will remove the blank line irrespective of its position from the line in consideration.


#### begin
/^.\{80\}/!{

:loop {
N;
/\n$/!bloop;
s/\n$//;
}
}
#### end.


thanks
