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.这是我在这里遇到的问题的延续.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仅Line feed用于换行:

\n

总之,只需更换每个出现\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 3

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 4

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

Answer 5

只需tr删除:

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

Answer 6

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

Answer 7

vim还可以将文件从 UNIX 格式转换为 DOS 格式。例如：

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

相反，如果您需要从 DOS 转到 UNIX：

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