Intro¶
Disadvantages of not having a final newline in files:
Some cli tools and other programs will miss the last line if it’s not terminated by a line feed.
It can mess up the git diff if you add to/after the last line as ideally you want a clear line delineation of the change.
How to find files without a final newline?¶
rg¶
Ripgrep is written in Rust, and Rust regexes provide \z to match “the end of text or file”.
See their docs.
$ rg --multiline --files-with-matches '[^\n]\z'
