--- title: "Concatenating PDF files on Linux" date: 2018-11-26 13:29:00 tags: ["snippets", "software", "formats", "linux"] --- A simple request, with an equally simple solution. Firstly I tried using my old favourite `pandoc` which will apparently only output PDF files, not input them. Some quick searching around lead me to `pdfunite` which did the job perfectly. Simple issue the following command to merge 3 files into one final output file: ``` pdfunite page-1.pdf page-2.pdf page-3.pdf pages-out.pdf ``` Be careful when specifying your files here as the last file will be overwritten if it already exists. If you don't have `pdfunite` installed, it's available via: ``` sudo apt-get install poppler-utils ```
