The command codesign --verify ${path-to-application_file.app} is used to verify the digital signature of an application file (.app) on macOS.

When an application is signed with a digital signature using a valid certificate, it ensures that the application hasn't been tampered with, and it verifies the identity of the developer or organization who signed it. This enhances security and trust.

Here is how the command works:

1. codesign is the command-line tool used for code signing operations in macOS.
2. --verify is the option used to perform the verification of the digital signature.
3. ${path-to-application_file.app} is the placeholder for the actual path to the application file (.app) that you want to verify. You need to replace it with the correct path, pointing to the specific application file you want to verify.

Once you run this command, it will verify the digital signature of the specified application file and provide feedback on its validity. This can help ensure that the application hasn't been modified or compromised since it was signed, offering assurance in the authenticity of the file.
