The command you provided, "adig -s ${1-2-3-4} ${example-com}", seems to be a combination of variables and text. However, without more context and understanding the purpose or context of the command, it is difficult to provide a precise explanation.

In general, here is what we can decipher:

1. "adig" is likely the name of a command or script.
2. "-s" is likely a flag or option for the "adig" command, but its specific meaning is unclear without further information about the command itself.
3. "${1-2-3-4}" appears to be a variable or argument placeholder. It is using the syntax of shell/bash scripting, where "$" signifies a variable and curly braces "{}" are used to enclose the variable name. In this case, it could potentially be used to represent an IP address or domain name.
4. "${example-com}" is most likely another variable or argument placeholder, using the same syntax as explained above. It seems to represent a domain name, specifically "example.com".

To fully understand the purpose and functionality of this command, further details about the "adig" command itself and the surrounding context would be necessary.
