How to use the command pbmlife (with examples)

The pbmlife command applies Conway’s Rules of Life to a PBM (Portable Bitmap) image. It takes an input PBM image file, applies the rules for one generation, and outputs the result as a PBM image file.

Use case 1: Apply the Rules of Life to an input PBM image file for one generation and output the result as a PBM image file

Code:

pbmlife path/to/file.pbm

Motivation: This use case is useful when you want to apply Conway’s Rules of Life to a PBM image and see the result.

Explanation: The pbmlife command is followed by the path to the input PBM image file (path/to/file.pbm in this example), which is the file you want to apply the rules to. The command then processes the image file and generates the output, which is a new PBM image file with the result of applying the rules for one generation.

Example output: The output of the command will be a new PBM image file that represents the result of applying Conway’s Rules of Life to the input image.

Use case 2: Display version

Code:

pbmlife -version

Motivation: This use case is helpful when you want to know the version of the pbmlife command you are using.

Explanation: The -version argument is used to instruct the pbmlife command to display the version information. When you run the command with this argument, it will output the version number of the pbmlife command.

Example output: The output of the command will be the version number of the pbmlife command, which can be useful for troubleshooting or ensuring you are using the correct version of the command.
