+# strip-final-newline [![Build Status](https://travis-ci.com/sindresorhus/strip-final-newline.svg?branch=master)](https://travis-ci.com/sindresorhus/strip-final-newline)
+
+> Strip the final [newline character](https://en.wikipedia.org/wiki/Newline) from a string/buffer
+
+Can be useful when parsing the output of, for example, `ChildProcess#execFile`, as [binaries usually output a newline at the end](https://stackoverflow.com/questions/729692/why-should-text-files-end-with-a-newline). Normally, you would use `stdout.trim()`, but that would also remove newlines at the start and whitespace.
+
+
+## Install
+
+```
+$ npm install strip-final-newline
+```
+
+
+## Usage
+
+```js
+const stripFinalNewline = require('strip-final-newline');
+
+stripFinalNewline('foo\nbar\n\n');
+//=> 'foo\nbar\n'
+
+stripFinalNewline(Buffer.from('foo\nbar\n\n')).toString();
+//=> 'foo\nbar\n'
+```
