There are a lot of software in Windows to merge PDF files but how can we do the same in Ubuntu?

pdftk

To merge two pdf files, file1.pdf and file2.pdf:

pdftk file1.pdf file2.pdf cat output mergedfile.pdf

More info available here^{Way Back Machine}.

To install, run:

sudo snap install pdftk

PDF Arranger (install), formerly known as PDF-Shuffler.

If you want a tool with a simple GUI, try pdfarranger. It allows for merging of PDFs as well as rearranging and deleting pages. For batch processing and/or more complicated tasks, pdftk is of course more powerful.

Ghostscript is a package (available by default in Ubuntu) that enables you to view or print PostScript and PDF files to other formats, or to convert those files to other formats.
To use Ghostscript to combine PDF files, type something like the following:

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dAutoRotatePages=/None -sOutputFile=finished.pdf file1.pdf file2.pdf

Here is a brief explanation of the command:

gs starts the Ghostscript program.
-dBATCH once Ghostscript processes the PDF files, it should exit. If you don't include this option, Ghostscript will just keep running.
-dNOPAUSE forces Ghostscript to process each page without pausing for user interaction.
-q stops Ghostscript from displaying messages while it works
-sDEVICE=pdfwrite tells Ghostscript to use its built-in PDF writer to process the files.
-sOutputFile=finished.pdf tells Ghostscript to save the combined PDF file with the specified name.
-dAutoRotatePages=/None Acrobat Distiller parameter AutoRotatePages controls the automatic orientation selection algorithm: For instance: -dAutoRotatePages=/None or /All or /PageByPage.

Your input files don't even need to be PDF files. You can also use PostScript or EPS files, or any mixture of the three.

There is a lot you can do with Ghostscript. You can read its documentation for more details.

You also also use pdfunite to merge pdf documents :

pdfunite in-1.pdf in-2.pdf in-n.pdf out.pdf

To install pdfunite if it is not installed already, run:

sudo apt-get install poppler-utils

PDF Chain

A very nice solution is PDFChain. It's GUI is a frontend of PDFTK where you can merge, split or even add some background to your PDF files.

An alternative approach is to use Latex as explained in this post (without root access assuming that you have pdflatex installed):

This is useful in case you do not have the mentioned tools nor root privileges, but you do have pdflatex.

I copy the tex code below to merge file1.pdf and file2.pdf. Create a file called output.tex and put:

\documentclass{article}
\usepackage{pdfpages}
\begin{document}
\includepdf[pages=-]{file1}
\includepdf[pages=-]{file2}
\end{document}

And to compile, simply use: pdflatex output.tex

The merged file will be named as output.pdf.

Give PDFMod a try, it’s from the GNOME project:

sudo apt install pdfmod

Use pdfsam it's very good for splitting and merging pdfs

sudo apt install pdfsam

I use pdfseparate to extract specific pages from big pdf file:

pdfseparate -f 156 -l 157 input.pdf output_%d.pdf
pdfseparate -f 1 -l 2 input.pdf output_%d.pdf 

and aftewards I join them all via command:

pdfunite $(ls -v output_*.pdf | tr '\n' ' ') out$(date +%Y-%m-%d_%H_%M_%S ).pdf

This joins:

output_1.pdf output_2.pdf output_156.pdf output_157.pdf 

into:

out2014-12-14_23_25_36.pdf

May be there is an easier way how to cope... :-)

Installation instructions:

sudo apt install poppler-utils

You can also use jPDFTweak, pdfsam or pdfjam.

(That said, I use pdftk.)

You can use pdftk to merge and modify PDF documents in general. Alternatively there's an online service to do just that:

Here is my approach:

• I wanted it to be easily accessible so I created a right-click shortcut in Nautilus (see )
• I wanted it to be very quick so I used pdfunite
• pdfunite only accepts the filepaths in the middle of the command so I had to scratch my head to manage the spaces in the filepaths. So I took the assumption that all filepaths will start with "/home/" and end with ".pdf"

Here is the result:

#!/bin/sh
CLEANED_FILE_PATHS=$(echo $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS | sed 's,.pdf /home/,.pdf\\n/home/,g')
echo $CLEANED_FILE_PATHS | bash -c 'IFS=$'"'"'\n'"'"' read -d "" -ra x;pdfunite "${x[@]}" merged.pdf'

Juste paste this script in

/home/your_username/.local/share/nautilus/scripts

and name it "merge_pdfs.sh" (for example). Then make it executable (right-click on merge_pdfs.sh -> Permissions tab -> tick "Allow executing file as a program"

So now to merge pdf files, you just have to select them -> right click -> scripts -> merge_pdfs.sh and it will create a "merged.pdf" file in the same directory

Hope it helps!

You can see use the free and open source pdftools (disclaimer: I am the author of it).

It is basically a Python interface to the Latex pdfpages package.

To merge pdf files one by one, you can run:

pdftools --input-file file1.pdf --input-file file2.pdf --output output.pdf

To merge together all the pdf files in a directory, you can run:

pdftools --input-dir ./dir_with_pdfs --output output.pdf
