### Rationale:
Since `[ str ]` checks that the string is non-empty, the space inside the quotes in the problematic code causes the test to always be true.
Since `[ str ]` checks that the string is non-empty, the space inside the quotes in the problematic code causes the test to always be true, since a string with a space can not be empty.
Sometimes this is also caused by overquoting an example, e.g. `[ "$foo -gt 0" ]`, which is always true for the same reason. The intention here was `[ "$foo" -gt 0 ]`.
