Two comments on this problem: 1) currently pdfxup does not handle several input files. Everything after the first PDf file is omitted. So the command above would work, but would be equivalent to $ pdfxup -l 28-11-2020-attestation-de-deplacement-derogatoire.pdf 2) I cannot reproduce the bug. Apparently, it occurred with v1.60 (lines 360-361 test the version number of ghostscript). It seems that your bash does not correctly interpret "${GSVERSION%.*}", which should return "9". Could you try (in bash) $ GSVERSION=9.53; echo "${GSVERSION%.*}" Best, -- Nico
