The command "ptx --references ${filename}" used in a terminal runs the "ptx" program with the specified "${filename}" and generates a report containing references to functions and variables used within the file.

Here's a breakdown of the command and its components:

• "ptx": This is the command itself, which is a program that analyzes and reports on the structure of a given executable file or object file.
• "--references": This is an option or flag passed to the "ptx" command, indicating that the program should generate a report specifically mentioning the references found within the file.
• "${filename}": This is a placeholder for the actual filename or path of the file you want the command to analyze. You need to replace "${filename}" with the appropriate file name or path you want to examine.

By executing this command, the "ptx" program will analyze the specified file and generate a report specifically listing the references to functions and variables present in that file. This can provide valuable information about the dependencies and usage of various code elements within the file.
