A simple Ghostscript command to merge two PDFs in a single file is shown below:
gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combine.pdf -dBATCH 1.pdf 2.pdf
Install Ghostscript:
Type the command sudo apt-get install ghostscript
to download and install the ghostscript package and all of the packages it depends on.
Any downside to using
-o
?Auto adds the -dBATCH and -dNOPAUSE ... Found in the docs here
gs -o combine.pdf -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress 1.pdf 2.pdf
