How to join two or more PDF files into one.

Hello linux users: in this post I will show how to join two or more PDF files into one. You will have to install the
Ghostscript driver using the following commands in your terminal (** On Debian based distros):

apt-get install gs
apt-get install pdftk

Now we join the PDFs with this command:

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=unidos.pdf file1.pdf  file2.pdf

Here is the explanation of command:

• gs:: Call to the Ghostscript program.
• -dBATCH: Close the Ghostscript when the process terminates.
• -dNOPAUSE: Don’t pause the program to ask for user interaction.
• -q: </strong>Don’t show messages during the process.
• -sDEVICE=pdfwrite: Use Ghostscript PDF generator to do the process.
• -sOutputFile=unidos.pdf: The name of the result file.

You can also join all PDF files in a directory by providing *.pdf as the input files.
