在不同平台结束的不同行背后的历史原因 [英] Historical reason behind different line ending at different platforms

问题描述

为什么DOS/Windows和Mac决定使用\ r \ n和\ r而不是\ n来结束行?这仅仅是试图与Unix有所不同"的结果吗?

Why did DOS/Windows and Mac decide to use \r\n and \r for line ending instead of \n? Was it just a result of trying to be "different" from Unix?

现在Mac OS X是Unix(类似)，Apple是否从\ r切换到\ n?

And now that Mac OS X is Unix (-like), did Apple switch to \n from \r?

推荐答案

DOS从CP/M继承了CR-LF行尾(您称呼\ r \ n，只是使ascii字符清晰可见). CP/M是从影响CP/M设计师Gary Kildall的各种DEC操作系统继承过来的.

DOS inherited CR-LF line endings (what you're calling \r\n, just making the ascii characters explicit) from CP/M. CP/M inherited it from the various DEC operating systems which influenced CP/M designer Gary Kildall.

使用CR-LF，以便电传打字机将打印头返回到左边距(CR =回车)，然后移至下一行(LF =换行).

CR-LF was used so that the teletype machines would return the print head to the left margin (CR = carriage return), and then move to the next line (LF = line feed).

Unix家伙在设备驱动程序中进行了处理，并在需要时将LF转换为CR-LF，输出到需要它的设备上.

The Unix guys handled that in the device driver, and when necessary translated LF to CR-LF on output to devices that needed it.

而且您猜到了，Mac OS X现在使用LF.

And as you guessed, Mac OS X now uses LF.
