swipl:tldr:c7833

This command swipl ${filename-pl} is used to run a Prolog program with the SWI-Prolog interpreter.

Here's the breakdown of the command:

• swipl is the command to invoke the SWI-Prolog interpreter. It stands for "SWI-Prolog interpreter."
• ${filename-pl} is a placeholder for the actual filename of your Prolog program. The .${filename-pl} syntax is commonly used to represent a variable or placeholder in command-line instructions. You need to replace ${filename-pl} with the actual name of your Prolog file, including the file extension .pl.

For example, if your Prolog program is named "hello.pl," the command would be:

swipl hello.pl

This command will execute the Prolog program using the SWI-Prolog interpreter and print any output or errors generated by the program.
