This article shows you how to send a document (e.g. a PDF file, an MP4 file, a WAV file, etc.) to a registered WhatsApp group from a shell script.

To send a PDF document to a WhatsApp group from a shell script, do this:

  1. First, learn how to send a simple text message to a group on the official site.
  2. With the above knowledge, you can now download our sample code.
  3. Locate the file bash/send-pdf-group.sh.
  4. Study the script and customize the TODO/FIXME lines.
    • Among other things, you must name your group creatively. Otherwise, the group may not receive the message.
  5. Change to the directory containing the script: cd bash
  6. Run the script to send the group the first PDF: ./send-pdf-group.sh

Happy coding :)
