Today I wanted to merge two PDF files into one final PDF document. On Ubuntu, this was harder than I thought. I have done this on Windows using Adobe and it was pretty simple. I decided that I will make this post so that I can always find the command when I am looking for it.
This is a command-line approach. I did not find a nice GUI approach, but if there is anyone out there who has found one, please feel free to leave a comment.
