The pdftotext command allows us to extract text from an entire PDF or from a particular page range. You could also use the kill command from the terminal to close it. When you use the mouse to close the xpdf window, it kills the process.

Note that we are also running the process in the background (using the ampersand on the command line) so we can continue to use our terminal while viewing PDFs.

You may have to enlarge the xpdf window a bit to see all the icons at the bottom. If you donвЂ™t have a GUI, you can view this document using xpdf.В Try searching for a word, say вЂChinaвЂ™, using the binoculars icon. Spend some time getting to know the capabilities of Okular, then skip ahead to the next section.] The ampersand runs the process in the background, allowing you to continue using your terminal while looking at the PDF.

Here we will use command line tools to extract text, images, page images and full pages from Adobe Acrobat PDF files. So it makes sense to try to convert our sources into text files whenever possible.В In the previous post weВ used optical character recognition (OCR) to convert pictures of text into text files. As a result, we have a very wide variety of powerful tools for manipulating and analyzing text files.
