# `MD047` - Files should end with a single newline character

Tags: `blank_lines`

Aliases: `single-trailing-newline`

Fixable: Some violations can be fixed by tooling

This rule is triggered when there is not a single newline character at the end
of a file.

An example that triggers the rule:

```markdown
# Heading

This file ends without a newline.[EOF]
```

To fix the violation, add a newline character to the end of the file:

```markdown
# Heading

This file ends with a newline.
[EOF]
```

Rationale: Some programs have trouble with files that do not end with a newline.
