Is there a way to create an actual docx file in bash that will just open as a blank Word document?
No sure how to create word document in bash, but if you just want to create some blank word document, you can manually create an empty document, then copy it to different file names.
one example to copy empty word document to files as 1.docx 2.docx ... 9.docx
for i in {1..9}; do cp empty.docx $i.docx; done
