The command you provided consists of several parts:

echo: This is a command used to display text or output a string. It is followed by the string "${digraph {this -> that} }", which will be passed as input to the next command.
| (pipe): This is a pipe symbol used to redirect the output of a command to the input of another command. In this case, the output of the echo command will be passed as input to the next command, osage.
osage: This is a command-line program that generates images from graph descriptions written in the DOT language, which is used to describe graph structures. It takes the graph description as input and generates an image based on it.
-T ${gif}: This flag is used to specify the output image format. In this case, it specifies that the output image should be in GIF format. ${gif} is likely a placeholder variable that should be replaced with the desired value, for example, gif to indicate the output should be in GIF format.
>: This is a redirect symbol used to save the output of a command into a file. In this case, the output of the osage command will be redirected and saved into the file specified by ${path-to-image-gif}. ${path-to-image-gif} is likely another placeholder variable that should be replaced with the desired file path.

To summarize, this command takes a graph description (in the form of a string "${digraph {this -> that} }"), passes it to the osage command to generate an image in GIF format, and saves the resulting image to a file specified by ${path-to-image-gif}.
