将换行格式从Mac转换为Windows

Question

我需要一个转换实用程序/脚本，它将在Mac上生成的.sql转储文件转换为Windows上可读的转储文件。这是我有here问题的延续。问题似乎是文本文件中的换行格式，但我找不到一个工具来进行转换...

Answer 1

Windows使用carriage return + line feed换行：

\r\n

Unix只使用Line feed换行：

\n

总之，简单地用\n替换\r\n的每一次出现。 在Mac OSX上默认不提供unix2dos和dos2unix。 幸运的是，你可以简单地使用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

Answer 2

这是一个非常简单的方法，对我来说很好，礼貌cat foo | col -b > foo2 ：

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

其中foo是在行尾有Control + M字符的文件，foo2是你正在创建的新文件。

Answer 3

扩展了Anne和JosephH的答案，在一个简短的perl脚本中使用perl，因为我懒得很快就输入perl-one-liner。 创建一个名为“unix2dos.pl”的文件，并将其放在路径中的目录中。编辑文件以包含2行：

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

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

$ unix2dos.pl xxx $ od -c xxx（检查它现在以cr lf结束） 0000000 h e l l o \ r \ n

Answer 4

在左侧面板的Xcode 9中打开/选择项目导航器中的文件。如果文件不存在，请将其放入项目导航器中。

在右侧面板中找到“文本设置”并将“行结束”更改为Windows（CRLF）。

Answer 5

这是Anne的答案的改进版本 - 如果您使用perl，您可以“就地”对文件进行编辑，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

Answer 6

您可以使用Homebrew安装unix2dos

brew install unix2dos

然后你可以这样做：

unix2dos file-to-convert

您还可以将dos文件转换为unix：

dos2unix file-to-convert

Answer 7

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unix2dos在DOS / Windows机器上运行cygwin，或使用MacPorts在Mac上运行tr。

Answer 8

只是做tr -d "\r" <infile.txt >outfile.txt 删除：

find ./ -type f -exec dos2unix {} \;

Answer 9

1. 用自制软件安装dos2unix
2. 运行vim以递归方式转换当前文件夹中的所有行结尾

Answer 10

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

还可以将文件从UNIX转换为DOS格式。例如：

#!/bin/bash
