以下情况:
我正在使用运行OS X的Mac,最近加入了一个项目,其成员到目前为止都使用Windows.我的第一个任务之一是在Git存储库中设置代码库,所以我从FTP中提取目录树并尝试将其检入我本地准备的Git仓库.在尝试这样做的时候,我得到的就是这个
fatal: CRLF would be replaced by LF in blog/license.txt.
因为这会影响"blog"文件夹下面的所有文件,所以我正在寻找一种方法,可以方便地将树中的所有文件转换为Unix行结尾.是否有一个开箱即用的工具或者我自己编写脚本？
作为参考,我的Git配置有关行结尾:
core.safecrlf=true core.autocrlf=input

dos2unix为你做到了这一点.相当直接的过程.
dos2unix filename
感谢toolbear,这里有一个单行代码,递归替换行结尾并正确处理空格,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.

假设您有GNU grep,perl这将在当前目录下的非二进制文件中以递归方式将CRLF转换为LF:
find . -type f -exec grep -qIP '\r\n' {} ';' -exec perl -pi -e 's/\r\n/\n/g' {} '+'
在当前目录下递归查找; 更改.为blog或whatev子目录以限制替换:
find .
仅匹配常规文件:
-type f
测试文件是否包含CRLF.排除二进制文件.grep为每个常规文件运行命令.这是排除二进制文件的代价.如果您有一个旧的,grep您可以尝试使用以下file命令构建测试:
-exec grep -qIP '\r\n' {} ';'
用LF替换CRLF.在'+'与第二-exec告诉find积累匹配的文件,并将它们传递给此命令的一个(或尽可能少)的调用-就像管道到xargs,但没有问题,如果文件路径包含空格,引号或其他shell元字符.在i在-pi告诉Perl修改文件就位.你可以使用sed或awk在这里做一些工作,你可能会将'+'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' {} '+'
这是一个更好的选择:Swiss File Knife.它以递归方式跨子目录工作,并正确处理空格和特殊字符.
你所要做的就是:
sfk remcr -dir your_project_directory
额外奖励:sfk还进行了大量其他转换.请参阅下面的完整列表:

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:提醒一句:在具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您的文件,特别是.git目录.如果是这种情况,请不要在整个文件夹中运行sfk,而是选择特定的文件扩展名(*.rb,*.py等).例:sfk remcr -dir chef -file .rb -file .json -file .erb -file .md
find . -not \( -name .svn -prune -o -name .git -prune \) -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;
这样更安全,因为它可以避免破坏你的git repo.使用.bzr,.hg或您使用的任何源控件添加或替换.git,.svn到非列表.
在OS X上,这对我有用:
find ./ -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;
警告:请在执行此命令之前备份您的目录.
