hi

cat untertitel.txt|sed -e '/^$/d'|sed 's/^RECORD.*$//g'

In the above line , i think you are deleting blank lines and replacing all the lines which starts with RECORD with null value ( Deletion is not taking place ).

The sed script may be like this:

sed -e '/^$/d' -e '/^RECORD/d' untertitel.txt

Thanks

Or with awk:

Code:
awk '/^RECORD/||!NF{next}1' file
