I get lots of e-bills (utility, telephone, Internet, mobile, cable and so on) in a PDF format for my small business and I need to forward those to my accountant. However, all PDFs files are password protected. I don’t want to share my account password with anyone to just open my bills. Evince is a PDF document viewer capable of displaying password protected files but it cannot remove the password. How do I remove a password from all PDFs under Ubuntu or any other Linux distribution in a batch mode?
