+## Expected another argument for this operator.
+
+### Problematic code:
+
+```sh
+[ $a -ne ]
+```
+
+### Correct code:
+
+```sh
+[ $a -ne $b ]
+```
+### Rationale:
+
+ShellCheck found a `test` operator without an operand. This could be a copy-paste fail, bad linebreak, or trying to use `<>` instead of `!=` or `-ne`. 
+
+### Exceptions:
+
+None.
