dos2Unix 和 python 脚本的区别
Difference dos2Unix and python script
我有要转换为 Unix 格式的文件。
我可以选择 python 转换方式的 differences/issues 是什么：
import sys
filename = sys.argv[1]
text = open(filename, 'rb').read().replace('\r\n', '\n')
open(filename, 'wb').write(text)
而不是：在子进程中调用 dos2unix Unix 命令？
谢谢！
来自man dos2unix：
The Dos2unix package includes utilities "dos2unix" and "unix2dos" to
convert plain text files in DOS or Mac format to Unix format and vice
versa.
In DOS/Windows text files a line break, also known as newline, is a
combination of two characters: a Carriage Return (CR) followed by a
Line Feed (LF). In Unix text files a line break is a single character:
the Line Feed (LF). In Mac text files, prior to Mac OS X, a line break
was single Carriage Return (CR) character. Nowadays Mac OS uses Unix
style (LF) line breaks.
Besides line breaks Dos2unix can also convert the encoding of files. A
few DOS code pages can be converted to Unix Latin-1. And Windows
Unicode (UTF-16) files can be converted to Unix Unicode (UTF-8) files.
...
-ascii
Convert only line breaks. This is the default conversion mode.
dos2unix 因此可以做的不仅仅是转换换行符，但默认行为仅此而已。
如果您的文件编码错误，您也必须使用 dos2unix 来处理它。
