+## Can't have empty do clauses (use `true` as a no-op)
+
+### Problematic code:
+
+```sh
+for i in 1 2 3; do
 done
+```
+
+### Correct code:
+
+```sh
+for i in 1 2 3; do
+  true
+done
+```
+
+### Rationale:
+
+An empty `do ... done` block is not valid.
+Use `true` or `:` if you need no command at all.
+
+### Exceptions:
+
+None.
