Question

How can a ppm file be opened using command line arguments?

1) By using the 'open' command followed by the file name
2) By using the 'open' command followed by the file name and the appropriate file extension
3) By using the 'open' command followed by the file name and the appropriate file format
4) By using the 'open' command followed by the file name and the appropriate command line arguments

Answer 1

To open a PPM file via the command line, use an image viewer's command specific to your operating system with the file name and path as arguments.

Step-by-step explanation:

To open a PPM (Portable Pixmap) file using command line arguments, typically you would not use the 'open' command. Instead, you would use a command that is specific to your operating system and possibly a command-line image viewer or editor that supports PPM files. For example, on a Unix-like system (such as Linux or macOS), you might use a program like 'display' from the ImageMagick suite of tools, or 'log' (Eye of GNOME) on GNOME desktop environments.

Here is an example of how you might open a PPM file on a Unix-like system:

1. Open your terminal or command line interface.
2. Type the command that corresponds to your installed image viewer followed by the file path, for example, display image.ppm or eog image.ppm.
3. Press Enter, and the file should open in the specified application.

If you're using Windows, you would likely use a third-party image viewer that can be invoked from the command line, passing the file name as an argument. For example, you could use IrfanView with a command like i_view32.exe image.ppm.

Remember that while using the command line, having the correct file path and extension is essential to successfully open the file.
