转换整个目录树的行结束符(Git)

dos2unix为你做这个。相当直截了当的过程 dos2unix filename < / p >

多亏了toolbear，这里有一个单行程序，可以递归地替换行结束符，并正确地处理空格、引号和shell元字符。

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

如果您使用的是dos2unix 6.0二进制文件将被忽略。

假设你有GNU grep和perl，这将递归地将当前目录下的非二进制文件中的CRLF转换为LF:

find . -type f -exec grep -qIP '\r\n' {} ';' -exec perl -pi -e 's/\r\n/\n/g' {} '+'

工作原理

在当前目录下递归查找;将.改为blog或whatev子目录来限制替换:

find .

只匹配常规文件:

  -type f

测试文件是否包含CRLF。排除二进制文件。为每个常规文件运行grep命令。这是排除二进制的代价。如果你有一个旧的grep，你可以尝试使用file命令构建一个测试:

  -exec grep -qIP '\r\n' {} ';'

将CRLF替换为LF。'+'和第二个-exec告诉find积累匹配的文件，并将它们传递给命令的一个(或尽可能少的)调用——就像管道到xargs，但如果文件路径包含空格、引号或其他shell元字符，则没有问题。-pi中的i告诉perl在适当的位置修改文件。你可以在这里使用sed或awk，并做一些工作，你可能会将'+'更改为';'，并为每个匹配调用一个单独的进程:

  -exec perl -pi -e 's/\r\n/\n/g' {} '+'

这里有一个更好的选择:瑞士锉刀。它在子目录间递归地工作，并正确地处理空格和特殊字符。

你所要做的就是:

sfk remcr -dir your_project_directory

额外的好处:sfk也做很多其他的转换。完整榜单如下:

All tree walking commands support file selection this way:


1. short format with ONE directory tree and MANY file name patterns:
src1dir .cpp .hpp .xml bigbar !footmp
2. short format with a list of explicite file names:
letter1.txt revenues9.xls report3\turnover5.ppt
3. long format with MANY dir trees and file masks PER dir tree:
-dir src1 src2 !src\save -file foosys .cpp -dir bin5 -file .exe


For detailed help on file selection, type "sfk help select".


* and ? wildcards are supported within filenames. "foo" is interpreted
as "*foo*", so you can leave out * completely to search a part of a name.
For name start comparison, say "\foo" (finds foo.txt but not anyfoo.txt).


When you supply a directory name, by default this means "take all files".


sfk list mydir                lists ALL  files of mydir, no * needed.
sfk list mydir .cpp .hpp      lists SOME files of mydir, by extension.
sfk list mydir !.cfg          lists all  files of mydir  EXCEPT .cfg


general options:
-tracesel tells in detail which files and/or directories are included
or excluded, and why (due to which user-supplied mask).
-nosub    do not process files within subdirectories.
-nocol    before any command switches off color output.
-quiet    or -nohead shows less output on some commands.
-hidden   includes hidden and system files and dirs.
For detailed help on all options, type "sfk help options".


beware of Shell Command Characters.
command parameters containing characters < > | ! & must be sur-
rounded by quotes "". type "sfk filter" for details and examples.


type "sfk ask word1 word2 ..."   to search ALL help text for words.
type "sfk dumphelp"              to print  ALL help text.

编辑:警告一句:在有二进制文件的文件夹上运行此命令时要小心，因为它将有效地破坏您的文件特别是.git目录. exe。如果这是你的情况，执行不在整个文件夹中运行sfk，但选择特定的文件扩展名(*。Rb， *.py，等等)。例如:sfk remcr -dir chef -file .rb -file .json -file .erb -file .md

在OS X上，这对我来说是可行的:

find ./ -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;

警告:执行此命令前请备份您的目录。

find . -not \( -name .svn -prune -o -name .git -prune \) -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;

这是更安全的，因为它避免破坏你的git回购。将.git， .svn添加或替换为.bzr， .hg或任何你使用的源代码控件到不列表中。

如果使用sed，这里有一个解决方案:

find . -type f -exec sed -i 's/\r$//' {} \;

-i代表in-place，如果你想创建备份，也可以使用-i.bak

's/\r$//'将替换每行末尾的所有回车(\r)

将所有行结束符转换为UNIX行结束符(LF)

dos2unix -v *

将所有行结束符转换为Windows行结束符(CRLF)

unix2dos -v *

-v/--verbose开关不是必需的，但是会输出哪些文件被转换到控制台。

dos2unix和unix2dos都是无处不在的轻量级工具，在我使用过的每一个类unix系统上都有，默认情况下它们跳过非文本文件，使得它们可以安全地以这种方式在整个目录上使用。

 find ./ -type f -name "*.java" -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;

这对我在wsl2上将所有java文件从CRLF更改为LF是有效的
