OSX断线

Question

一组(DOS) ANSI-C文本文件(点击此处下载)被复制到OSX笔记本电脑上。我希望确保CR\LF不会成为编译文件的障碍。崇高和vi似乎正确地显示了这些文件。

三个终结者是：

1. 默认情况下，Mac使用单个回车(CR)，表示为\r。
2. 另一方面，Unix使用单个linefeed (LF) \n。
3. Windows更进一步并同时使用，创建了一个(CRLF)组合\r\n。

安装了dos2unix：

brew install dos2unix

尝试处理ANSI文件返回错误：

$ dos2unix *.h
dos2unix: Binary symbol 0x1A found at line 75
dos2unix: Skipping binary file error.h
dos2unix: Binary symbol 0x1A found at line 156

dos2unix: Skipping binary file sim_lib.h
dos2unix: Binary symbol 0x1A found at line 27
dos2unix: Skipping binary file stats.h

.c文件

$ dos2unix *.c
dos2unix: Binary symbol 0x1A found at line 110
dos2unix: Skipping binary file error.c
dos2unix: Binary symbol 0x1A found at line 780

问题

要确保正确的终止符被应用，需要采取哪些步骤？

如何才能可视化(核实)哪个终结者正在参与？(CR \ LF \ CRLF)

更新

-f (force)标志将忽略0x1A并处理该文件。递归查找.c文件：

user@hostname:~/csim$ find . -name '*.c' | xargs dos2unix -f

Answer 1

下面是一个简单的测试：

~/tmp$ printf "\x1Aabc\r\n" > test
~/tmp$ od -a test
0000000  sub   a   b   c  cr  nl                                        
0000006
~/tmp$ dos2unix test
dos2unix: Binary symbol 0x1A found at line 1
dos2unix: Skipping binary file test
~/tmp$ dos2unix -f test
dos2unix: converting file test to Unix format...
~/tmp$ od -a test
0000000  sub   a   b   c  nl                                            
0000005

。使用dos2unix -f强制转换

。使用od -a查看二进制文件

。麦克上的终结者也是LF。
