How to understand c# test task correctly?

Question

.NET

Guys, hello everyone.
The test task contains the following paragraph:
The name of the input, output file, sorting mode, as well as the content type are set at
startup through command line arguments. Windows command line examples:
sort-it.exe in.txt out.txt -i -a (for integers in ascending order)
sort-it.exe in.txt out.txt -i -d (for integers in ascending order) descending)
sort-it.exe in.txt out.txt -s -a (for ascending lines)
Please do not judge strictly - the newbie is green.
Tell me on your fingers how should I interpret this? those. do I need to read this string, then split it into substrings, which will be input values ​​for other methods (reading a file, sorting)?
