Answer 1

This is how I do it:
First line convert all jpg files to pdf it is using convert command.
Second line is merging all pdf files to one single as pdf per page. This is using gs ((PostScript and PDF language interpreter and previewer))

for i in $(find . -maxdepth 1 -name "*.jpg" -print); do convert $i ${i//jpg/pdf}; done
gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=merged_file.pdf -dBATCH `find . -maxdepth 1 -name "*.pdf" -print"`
