The `pdfinfo` command is a command-line utility used to extract metadata and information from Portable Document Format (PDF) files. It analyzes a given PDF file and displays a comprehensive report including details such as the PDF version, file size, number of pages, encryption status, creator, producer, title, author, subject, keywords, creation date, modification date, tagged status, form status, javascript status, file structure optimization, page size and rotation, and more. This information is valuable for assessing the properties of a PDF document, identifying its origins, and understanding its characteristics.
The command is part of the Poppler PDF rendering library, a widely used open-source project for working with PDF documents.
The tool provides a quick and easy way to obtain crucial details about a PDF without opening the file in a PDF viewer, making it useful for scripting and automation.

Some information, such as the producer and creator applications, may be intentionally omitted or obfuscated by the PDF author. The accuracy of date information also depends on the PDF's creation process.

Pdfinfo exits with the following status code:
0: No error.
>0: An error occurred.

The `pdfinfo` command is part of the Poppler library, a free software utility for rendering PDF documents. Poppler was initially derived from the xpdf project but evolved into its own independent codebase. `pdfinfo` has been actively maintained and improved over the years along with the Poppler library, becoming a standard tool for extracting information from PDF files across various Linux distributions and other operating systems.
