+        Unix convention seems to prefer the hyphen -v for single-letter parameters,
+        and double hyphen --verbose for multi-letter parameters.

+        I tend to prefer hyphens, as they are more OS-agnostic (forward slashes are
+        path delimiters in some OSes) and used in more modern Windows apps
+
+        One reason for continuing to use the single letter options is because they can be strung together:
+        ls -ltr is a lot easier to type than ls --format=long --sort=time --reverse
