odt's to image-embedded html's

Hello everybody,

Sorry for disturbing you but I'm in need of some help (was trying to 
Google but without much success).

Given:

 * Lubuntu 18.04
 * LO 6.0

I have a bunch of odt files (in one folder). I need to convert all of 
them to html files with embedded images. I was trying to use a code like 
the following:

/for f in *.odt; do echo "Processing $f"; libreoffice6.0 --writer "$f"; 
soffice --convert-to html:HTML:EmbedImages "$f"; done/

but without success. Maybe somebody of you can help me to figure out how 
to write an appropriate code?

Thank you in advance!
