By above two command line, we can merge PDF file in two ways.
pdftoolbox *.pdf -merge -outfile combined.pdf
By this command line, we can merge PDF file in batch using wild character. By this method, you can merge a whole folder or directory PDF files into one PDF file.
pdftoolbox in.pdf -merge 1R 2-end -outfile out.pdf
pdftoolbox in.pdf -merge 1E 2-end -outfile out.pdf
By those above two command line templates, we can rotate PDF clockwise and then merge PDF file.
pdftoolbox in.pdf -merge 1-endS -outfile out.pdf
By this command line, we can rotate the whole PDF file page in 180 degree and then merge files.
