a) you dropped the necessary sed -rn options.
b) drop the trailing file in the long line.
c) in s/^$/d/, there's an s and the trailing / too many.

Thank you RudiC for your support.

For clarification: - it works.

The updated script-file:

Code:
s/^$/d/
/^[a-zA-Z]/d
/[0-9]{4}(\.[0-9]{2}){2}, [[:alpha:]]+/ {h;n;}; H; x; s/\n/\t/; p; G; s/\n/\t/; s/(.*)(\t.*)\2/\1/; x;

The command:

Code:
sed -rn -f script-file file

.

You still have the s/^$/d/ that puts a d on empty lines. While /^$/d deletes empty lines.
