You see this in US tax documents, RPG character sheets, online school workbooks, and other PDF files that are intended to be interactive. If you need to split a PDF into single-page files, there's a special action for that, called burst: $ pdftk book.pdf burstįew would argue that the PDF format hasn't become bloated over the years, and one feature you sometimes find in a PDF file is a fillable form. You can split a PDF by sending the pages you want to a new file: $ pdftk book.pdf \ Splitting a PDF file into many different files also uses the cat action, and it's similar in principle to removing pages. The page I've removed, therefore, is page 2. In this example, page 1 of my book file, and all pages from 3 to the end, are saved to a new file. You can't exactly remove a page from a PDF, but you can create a new PDF containing only the pages you want to keep. In this example, the action is cat, as in concatenate and like the Linux cat command, it concatenates one or more PDF files into a single data stream, and the data stream is directed into whatever file the output argument specifies. However, it's also possible to prepend the cover to a PDF with pdftk-java: $ pdftk cover.pdf body.pdf \ A good desktop publisher like Scribus makes it easy just to reference an image so that when the cover changes, it's automatically updated in layout. You could combine the two in your layout application. It's not uncommon for the front cover of a book to be created in a separate application, such as Inkscape or GIMP, than the rest of the book, which is usually done in a layout application like Scribus or an office suite like LibreOffice. It's the action part that's most complex, so I'll start with simple tasks. output: Where you want to save your modified PDF file.action: What you want to do to the input file.The syntax is a little unusual because it doesn't use traditional-style terminal options, but with practice, it's not too difficult to remember. The structure of a valid pdftk-java command follows a pattern, but there's a lot of flexibility in what's in the pattern. ![]() Load your new Bash settings: $ source ~/.bashrc Command syntax Open ~/.bashrc in your favorite text editor and add this line to it: alias pdftk='java -jar $HOME/.local/bin/pdftk-all.jar'ģ.
