The command "subfinder -d ${example-com}" is used to invoke a tool called "subfinder" with the "-d" option followed by a domain name variable.

Here's a breakdown of the command:

• "subfinder": This is the name of the tool or command-line utility that the user wants to execute.
• "-d": This flag or option denotes that the user wants to provide a domain name as an argument.
• "${example-com}": This is a placeholder or variable that should be replaced with a specific domain name. The format used here is "${placeholder}".

When executing the command, the user should replace "${example-com}" with an actual domain name. For example, if the user wants to find subdomains for "example.com", they would replace "${example-com}" with "example.com" like this: "subfinder -d example.com".

The purpose of the "subfinder" tool is to discover subdomains associated with a given domain. By providing the domain name as an argument, the tool will check for any subdomains that may exist and display them as an output.
