sed: Find pattern and delete 5 lines after it

Hello all

I am trying to edit a print file.

For every occurence of the ^L form feed character I need to remove 5 blank lines after it but still keep the ^L.

I am a rare user of sed and am ok with the basics but am struggling with this.

Can anybody point me in the right direction please?

Many thanks
Paul

Code:

sed '/<regex>/{p;N;N;N;N;N;d}' <file>

slight change worked for me:

Code:

sed -i '/<regex>/{n;N;N;N;N;d}' <file>

When I tried the above it took out the regex line as well
