The task is: "Remove the first two lines that don't begin with "@" from a file." Actually, the grep-thing I offered will also delete copies of these two lines that occur in another place. That should be no problem if the file is something like @comment deleteme deleteme @comment data: x-y-dy However, if this is not the case, it cannot be done this way. How would you do it with sed?
