Concatenate PDFs on the Command Line
Concatenate PDF’s on the Command Line
I used to use pdfchain to concatenate PDF files. It’s a GUI based program that gets the job done and can do a few other things as well.
But for simple concatenating jobs, it’s just easier, and quicker, to use the command line.
There’s a couple of programs that I routinely use: gs (ghostscript) and pdftk.
