PDF-Combiner
Introduction
Tired of opening online-pdf-combiner to combine PDF files.
Installation
Use PyInstaller to build standalone executable.
The one in repo was build under macOS High Sierra v10.13.6
Usage
Run the command followed by bunch of PDF files to be combined
pdf-combine 1.pdf 2.pdf 3.pdf ...than combined.pdf will generate at current directory
Note: Drag files into terminal will save lots of time
Postscript
Just found out I got PDFjam installed few seconds before git push LOL.
