The command "pdfinfo" is a command-line tool that is used to retrieve information about a PDF file. It allows you to view various details such as the title, author, creation date, page count, file size, and many more.
In the command "pdfinfo ${filename-pdf}", "${filename-pdf}" is a placeholder that needs to be replaced with the actual path or name of the PDF file you want to get information about. The argument specifies the file you want to examine with the pdfinfo command.
So, for example, if you have a PDF file named "sample.pdf" and you want to get its information using the pdfinfo command, you would replace "${filename-pdf}" with "sample.pdf". The command would then look like: "pdfinfo sample.pdf".
Executing this command will display a series of details about the specified PDF file, providing a comprehensive overview of its attributes.
