Using pdftotext:#

1. Installation:

   • If it’s not installed, you’ll need to install the poppler-utils package which includes pdftotext.

   sudo apt install poppler-utils

   or

   yum install poppler-utils

   depending on your distribution.

2. Usage:

   • Once installed, you can convert a PDF to text and then count the words as follows:

   pdftotext input.pdf - | wc -w

   Here, input.pdf is your source PDF file, and wc -w counts the number of words. The - in pdftotext specifies that the output should be sent to stdout, which is then piped into wc.
