missing-newline-at-end-of-file (S002)

Fix is always available.

This rule is turned on by default.

What does it do?

Checks for the absence of a new line at the end of the file.

Why is this bad?

POSIX standards state that a line is a sequence of characters ending with a newline character. Some tools may not handle files that do not end with a newline correctly, leading to potential issues in file processing, version control diffs, and concatenation of files.
