pdfunite *.pdf ALL.pdf

  "pdfunite" is part of the "poppler-utils" package on Debian-based systems. (But older versions of poppler-utils don't include pdfunite, so the "gs" solution might still be useful.)

  Similarly for pdftk: pdftk *.pdf cat output combined.pdf It can perform lots of other functions on pdfs (hence the name!) during the process like setting printing permissions and quality, and performing encryptions.
