将换行格式从Mac转换为Windows

我需要一个转换实用程序/脚本，它将Mac上生成的.sql转储文件转换为Windows上可读的文件。这是我在这里遇到的问题的延续。问题似乎与文本文件中的换行符格式有关，但我找不到进行转换的工具...

Windows 对换行符使用carriage return+ line feed：

\r\n

Unix仅Line feed用于换行符：

\n

总之，只需更换的每一次出现\n的\r\n。
两者unix2dos并dos2unix没有通过在Mac OSX上可用的默认值。
幸运的是，您可以简单地使用Perl或sed完成以下工作：

sed -e 's/$/\r/' inputfile > outputfile                # UNIX to DOS  (adding CRs)
sed -e 's/\r$//' inputfile > outputfile                # DOS  to UNIX (removing CRs)
perl -pe 's/\r\n|\n|\r/\r\n/g' inputfile > outputfile  # Convert to DOS
perl -pe 's/\r\n|\n|\r/\n/g'   inputfile > outputfile  # Convert to UNIX
perl -pe 's/\r\n|\n|\r/\r/g'   inputfile > outputfile  # Convert to old Mac

来自以下代码段：http :
//en.wikipedia.org/wiki/Newline#Conversion_utilities

这是Anne答案的改进版本-如果使用perl，则可以对文件进行“就地”编辑，而不是生成新文件：

perl -pi -e 's/\r\n|\n|\r/\r\n/g' file-to-convert  # Convert to DOS
perl -pi -e 's/\r\n|\n|\r/\n/g'   file-to-convert  # Convert to UNIX

您可以使用Homebrew安装unix2dos

brew install unix2dos

然后，您可以执行以下操作：

unix2dos file-to-convert

您也可以将dos文件转换为unix：

dos2unix file-to-convert

您可能想要unix2dos：

$ man unix2dos

NAME
       dos2unix - DOS/MAC to UNIX and vice versa text file format converter

SYNOPSIS
           dos2unix [options] [-c CONVMODE] [-o FILE ...] [-n INFILE OUTFILE ...]
           unix2dos [options] [-c CONVMODE] [-o FILE ...] [-n INFILE OUTFILE ...]

DESCRIPTION
       The Dos2unix package includes utilities "dos2unix" and "unix2dos" to convert plain text files in DOS or MAC format to UNIX format and vice versa.  Binary files and non-
       regular files, such as soft links, are automatically skipped, unless conversion is forced.

       Dos2unix has a few conversion modes similar to dos2unix under SunOS/Solaris.

       In DOS/Windows text files line endings exist out of a combination of two characters: a Carriage Return (CR) followed by a Line Feed (LF).  In Unix text files line
       endings exists out of a single Newline character which is equal to a DOS Line Feed (LF) character.  In Mac text files, prior to Mac OS X, line endings exist out of a
       single Carriage Return character. Mac OS X is Unix based and has the same line endings as Unix.

您可以unix2dos使用cygwin在DOS / Windows计算机上运行，也可以使用MacPorts在Mac上运行。

只需tr删除：

tr -d "\r" <infile.txt >outfile.txt

1. 使用自制软件安装dos2unix
2. 运行find ./ -type f -exec dos2unix {} \;以递归方式转换当前文件夹中的所有行尾

vim还可以将文件从UNIX转换为DOS格式。例如：

vim hello.txt <<EOF
:set fileformat=dos
:wq
EOF

以下是基于上述答案以及健全性检查的完整脚本，并且可以在Mac OS X上运行，并且也可以在其他Linux / Unix系统上运行（尽管尚未经过测试）。

这是一种非常简单的方法，对我来说很有效，由Davy Schmeits的Weblog提供：

cat foo | col -b > foo2

其中foo是该行末尾具有Control + M字符的文件，而foo2是您要创建的新文件。

在优胜美地OSX上，使用以下命令：

sed -e 's/^M$//' -i '' filename

其中^M序列通过按压来实现Ctrl+ V然后Enter。

在简短的perl脚本中使用perl扩展了Anne和JosephH的答案，因为我太懒了以至于无法立即输入perl-one-liner。
创建一个文件，例如“ unix2dos.pl”，并将其放在路径中的目录中。编辑文件以包含两行：

#!/usr/bin/perl -wpi
s/\n|\r\n/\r\n/g;

假设“哪个perl”在您的系统上返回“ / usr / bin / perl”。使文件可执行（chmod u + x unix2dos.pl）。

示例：
$ echo“ hello”> xxx
$ od -c xxx（检查文件是否以nl结尾）
0000000 hello \ n

$ unix2dos.pl xxx
$ od -c xxx（检查它现在以cr lf结尾）
0000000 hello \ r \ n

在左侧面板的Xcode 9中，在项目导航器中打开/选择文件。如果文件不存在，则将其拖放到项目导航器中。

在右侧面板上找到“ 文本设置”，然后将“ 行尾”更改为Windows（CRLF）。
