dos2unix不转换^ M [英] dos2unix doesn't convert ^M

问题描述

我从Windows 7上运行的程序中将结果导出到文本文件中，并将该文件复制到Xubuntu 14.04上.在终端中，我运行了dos2unix file.txt，告诉我converting file out_mapqtl.txt to Unix format.但是，当我用less查看文件时，我仍然看到Windows的行尾为^ M，并且wc -l返回我为"0".

I exported results in a text file from a program running on Windows 7, and copied the file on Xubuntu 14.04. In a terminal, I ran dos2unix file.txt, which tells me converting file out_mapqtl.txt to Unix format. However, when I look at the file with less, I still see the Windows end-of-line as ^M, and wc -l returns me "0".

我尝试了此处所述的几种方法，但均无效果.然后，我在Vim中打开文件，并按照有的说明进行了:%s/\r/\r/g的操作，效果很好.那么，为什么dos2unix不起作用?有办法避免每次打开Vim吗?

I tried several things described here, but none works. I then opened the file in Vim and did :%s/\r/\r/g as explained there, which worked fine. So any idea why dos2unix didn't work? Would there be a way to avoid opening Vim every time?

推荐答案

\r表示回车符，在MAC上不带\n表示换行符.您确定文件是DOS(\r\n)格式而不是MAC(\r)格式吗?

\r denotes a carriage return, and on MAC it is used without \n to denote a line break. Are you sure the file is in DOS (\r\n) format and not MAC (\r)?

如果VIM确实是唯一可以修复文件的内容，则还可以通过以下方式调用它:

If VIM really turns out to be the only thing that'll repair your files, you can also invoke it as:

vim somefile.txt +"%s/\r/\r/g" +wq

这将打开文件，执行操作，保存，然后退出.

This will open the file, perform the operation, save it, then quit.

您可以举一个文件示例，以便我们进行进一步调查吗?

Can you give us an example of the file, so that we can investigate further?
