Bug Description

For non-FIL_PAGE_TYPE_BLOB pages, page_parser emits filenames in the format It zero pads the page ID to 8 places, but does not pad the internal ID.

The page concatenation step in the documentation ( recommends using the following command:

find pages-1246363747/0-286/ -type f -name '*.page' | sort -n \
   | xargs cat > pages-1246363747/0-286/customer_pages_concatenated

However, because the prefixed ID is not padded, the sort command used can result in an output file containing out or order pages.

The attached patch resolves the sort order issue by zero padding the prefix ID.
