+## Instead of '[ true ]', just use 'true'.
+
+### Problematic code:
+
+    if [ true ]
+    then
+      echo "always triggers"
+    fi
+
+### Correct code:
+
+    if true
+    then
+      echo "never triggers"
+    fi
+
+### Rationale:
+
+This is a stylistic suggestion to use `true` instead of `[ true ]`. 
+
+`[ true ]` seems to suggest that the value "true" is somehow relevant to the statement. This is not the case, it doesn't matter. You can replace it with `[ false ]` or `[ wombat ]`, and it will still always be true:
+
+    String  | In brackets  | Outside brackets
+    --------+--------------+-----------------
+    true    | true         | true
+    false   | true         | false
+    wombat  | true         | unknown command
+
+It's therefore better to use it without brackets, so that the "true" actually matters.
+
+### Exceptions:
+
+None.
