# Line Endings Converter

> Convert between CRLF, LF and CR, and strip trailing whitespace.

Line endings differ by platform: Unix and macOS use LF, Windows uses CRLF, and classic Mac OS used a bare CR. Mixed endings in one file break diffs, shell scripts and some parsers. This converter normalises them all and can strip trailing whitespace at the same time.

## FAQ

### Why does my shell script fail with a strange error?

Almost certainly CRLF line endings. The shebang line becomes "#!/bin/bash\r", and the interpreter looks for a program whose name ends in a carriage return. Converting to LF fixes it immediately.
