将换行格式从Mac转换到Windows
我需要一个转换实用程序/脚本，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一个问题的延续。 这个问题似乎与文本文件中的换行格式，但我找不到一个工具来进行转换…
Windows使用carriage return +换行换行符：
\r\n
Unix只使用换行换行：
\n
总之，简单地用\r\n来代替\n的每一次出现。
在Mac OSX上， unix2dos和dos2unix都不是默认可用的。
幸运的是，您可以简单地使用Perl或sed来完成这项工作：
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

这是Anne的答案的一个改进版本 – 如果你使用Perl，你可以在文件上就地编辑，而不是生成一个新的文件：
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
你可以用Homebrew安装unix2dos
brew install unix2dos
那么你可以这样做：
unix2dos file-to-convert
你也可以把dos文件转换成unix：
dos2unix file-to-convert
你可能想要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.
您可以使用cygwin在DOS / Windows计算机上运行unix2dos ，也可以在Mac上使用MacPorts运行 。
只要做tr删除：
tr -d "\r" <infile.txt >outfile.txt
在优胜美地OSX上，使用这个命令：
sed -e 's/^M$//' -i '' filename
^M序列是通过按Ctrl + V然后回车来实现的 。
- 用自制软件安装dos2unix
- 运行'find ./ -type f -exec dos2unix {} \;' recursion地转换当前文件夹内的所有行结束符
vim也可以将文件从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的完整脚本，以及完整性检查，适用于Mac OS X，并且还可以在其他Linux / Unix系统上工作（虽然尚未经过testing）。

这是一个非常简单的方法，对我来说很好， Davy Schmeits的博客提供 ：
cat foo | col -b > foo2
foo是在行尾有Control + M字符的文件，foo2是您创build的新文件。
在安妮和约瑟夫（JosephH）的答案中，用perl脚本使用perl，因为我懒得打出perl-one-liner的时间。
创build一个名为“unix2dos.pl”的文件，并将其放在path中的一个目录中。 编辑文件以包含2行：
#!/usr/bin/perl -wpi s/\n|\r\n/\r\n/g;
假设“perl”在你的系统上返回“/ usr / bin / perl”。 使文件可执行（chmod u + x unix2dos.pl）。
例：
$ echo“hello”> xxx
$ od -c xxx（检查文件以nl结尾）
0000000 hello \ n
$ unix2dos.pl xxx
$ od -c xxx（检查它现在结束）
0000000 hello \ r \ n
