We can then select different pages from these files, and even perform different operations on them. Instead of referring to the different files directly by name, we create aliases, called ‘handles’, for the different files.

If all of the files are sequentially numbered or named, and in the same directory, wildcards can be used instead of typing the name of each file individually. $ pdftk 1.pdf another.pdf 3.pdf yet-another.pdf fifth.pdf output combined.pdf We only have to provide a space separated list of files, in the order you wish to add them, and the name of the output file.
The process of merging multiple PDF files into a single document is fairly straightforward with PDFtk. $ sudo apt install pdftk How to use PDFtk
