+## This variable is assigned to itself, so the assignment does nothing.
+
+### Problematic code:
+
+```sh
+var="$var"
+```
+
+### Correct code:
+
+```sh
+# If the goal is to do nothing
+true
+```
+
+### Rationale:
+
+ShellCheck found a variable that is assigned to itself, e.g. `x=$x`. This obviously has no effect.
+
+Double check what the assignment was supposed to do. 
+
+### Exceptions:
+
+None.
