| |
| > 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' |
| ``` |
