+## Use 'false' instead of empty [/[[ conditionals.
+
+### Problematic code:
+
+```sh
+if [ ]
+then
+  echo "Temporarily disabled"
+fi
+```
+
+### Correct code:
+
+```sh
+if false
+then
+  echo "Temporarily disabled"
+fi
+```
+### Rationale:
+
+`[ ]` is a somewhat obscure way of expressing falsehood, and the behavior is likely intended to allow the incorrectly quoted command `[ $var ]` to still work when the variable is unset.
+
+POSIX has a more descriptive command `false` for this.
+
+### Exceptions:
+
+None. This is a stylistic suggestion, and has no effect on how the script works.
