The command "okular --presentation ${filename}" launches the Okular application in presentation mode with a specified PDF file.

Here's a breakdown of the command:

• "okular" refers to the executable file of the Okular application, which is a popular document viewer that supports various formats, including PDF.
• "--presentation" is a command-line option specific to Okular. When used, it opens the specified file in presentation mode, providing a full-screen view suitable for presenting the document.
• "${filename}" is a placeholder for the actual name of the file you want to open with Okular. It is meant to be substituted with the appropriate filename when running the command.

To use the command, you need to replace "${filename}" with the actual name and path of the PDF file you want to open. For example, if you have a file called "presentation.pdf" located in your home directory, you would run:

okular --presentation ~/presentation.pdf

This would launch Okular in presentation mode, displaying the "presentation.pdf" file.
