The command "xpdf -fullscreen ${filename-pdf}" is used to open a PDF file in fullscreen mode using the xpdf application.
Let's break down the command:
-
"xpdf" is the name of the application or command-line tool used to open PDF files. It is typically available on Linux systems.
-
"-fullscreen" is a command-line option passed to xpdf, instructing it to open the PDF in fullscreen mode. This means that the PDF will occupy the entire screen, hiding the taskbar or any other visible elements of the desktop.
-
"${filename-pdf}" represents the variable that holds the name of the PDF file you want to open. The exact variable name may vary depending on the context in which this command is being used. You would replace this variable with the actual name of the PDF file you want to open. Note that the file extension is ".pdf".
To use this command, you need to have xpdf installed on your system. You can open a terminal or command prompt, navigate to the directory where your PDF file is located, and then run the "xpdf -fullscreen ${filename-pdf}" command, replacing "${filename-pdf}" with the name of your actual PDF file. This will launch xpdf and open the PDF file in fullscreen mode.
