+## getopts specified -n, but it's not handled by this 'case'.
+
+### Problematic code:
+
+```sh
+while getopts "vrn" n
+do
+  case "$n" in
+    v) echo "Verbose" ;;
+    r) echo "Recursive" ;;
+    *) usage;;
+  esac
+done
+```
+
+### Correct code:
+
+```sh
+while getopts "vrn" n
+do
+  case "$n" in
+    v) echo "Verbose" ;;
+    r) echo "Recursive" ;;
+    n) echo "Dry-run" ;;    # -n handled here
+    *) usage;;
+  esac
+done
+```
+### Rationale:
+
+You have a `while getopts` loop where the corresponding `case` statement fails to handle one of the flags.
+
+Either add a case to handle the flag, or remove it from the `getopts` option string.
+
+### Exceptions:
+
+None.
