Line Endings

In DOS/Windows, a line break is Carriage Return + Line Feed \r\n. In Unix (Linux, Mac OS X), a line break is Line Feed \n. In Classic Mac OS, Commodore and TRS-80, a line break was CR \r. I encountered errors while compiling MAME due to uniformity.

dos2unix is a common utility, but I like to use endlines. It's very simple and supports checking and recursive.

endlines

Install endlines

endlines may be compiled on Linux, Mac OS X, and IBM AIX.

$ cd ~/
$ curl -Lo endlines192.zip "https://github.com/mdolidon/endlines/archive/1.9.2.zip" && unzip endlines192.zip && mv endlines-master endlines192
$ cd endlines192
$ make
$ make test
$ sudo make install

Convert Line Endings

WARNING: You must cd (change directory) to your target directory before issuing a command to convert files. There is no confirmation. In the following example, we will use the mame0215 directory.

$ cd ~/mame0215
$ endlines check * -r # Will check all files in directory
$ endlines unix * -r # Convert all files in directory to unix format, recursively
