整个目录树（Git）的换行结束
以下情况：
我正在运行OS X的Mac，最近join了一个项目，其成员目前都使用Windows。 我的首要任务之一是在Git仓库中设置代码库，所以我从FTP中取出了目录树，并试图将其检入到本地准备好的Git仓库中。 当试图做到这一点，我得到的只是这个
fatal: CRLF would be replaced by LF in blog/license.txt. 由于这会影响“blog”文件夹下的所有文件，因此我正在寻找一种方法将树中的所有文件转换为Unix行尾。 有没有开箱即用的工具，或者我自己写脚本？
作为参考，我的Gitconfiguration关于行尾：
core.safecrlf=true core.autocrlf=input
dos2unix为你做的。 相当直接的过程。
dos2unix filename
感谢toolbear，这是一个recursion地replace行尾的单行程，并正确处理空格，引号和shell元字符。
find ./ -type f -exec dos2unix {} \;
如果你使用的是dos2unix 6.0，二进制文件将被忽略。
假设你有GNU grep和perl这将在当前目录下的非二进制文件中recursion地将CRLF转换为LF：
find . -type f -exec grep -qIP '\r\n' {} ';' -exec perl -pi -e 's/\r\n/\n/g' {} '+'
怎么运行的
在当前目录下recursion查找; 改变. 以blog或whatev子目录来限制更换：
find .
只匹配常规文件：
-type f
testing文件是否包含CRLF。 排除二进制文件。 对每个常规文件运行grep命令。 这是排除二进制文件的价格。 如果你有一个老的grep你可以尝试使用file命令来build立一个testing：
-exec grep -qIP '\r\n' {} ';'
用LFreplaceCRLF。 第二个-exec的'+'告诉find来积累匹配的文件，并将它们传递给一个（或尽可能less的）命令的调用，比如pipe道到xargs ，但是如果文件path包含空格，引号或者其他shell元字符。 i在-pi告诉perl修改文件到位。 你可以在这里用sed或awk做一些工作，你可能会把'+'改成';' 并为每个匹配调用一个单独的进程：
-exec perl -pi -e 's/\r\n/\n/g' {} '+'
这是一个更好的select： 瑞士文件刀 。 它在子目录之间recursion地工作，并且适当地处理空格和特殊字符。
你所要做的就是：
sfk remcr -dir your_project_directory
奖金： sfk也做了很多其他的转换。 见下面的完整列表：

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：一个谨慎的话：在有二进制文件的文件夹上运行时要小心，因为它会有效地破坏你的文件， 尤其是.git目录 。 如果是这种情况，请不要在整个文件夹中运行sfk，而是select特定的文件扩展名（* .rb，* .py等）。 例如： sfk remcr -dir chef -file .rb -file .json -file .erb -file .md
在OS X上，这为我工作：
find ./ -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;
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，因为它避免了腐蚀你的git回购。 添加或replace.git，.svn与.bzr，.hg或任何源代码控制你使用的不是列表。
