Windows PATH to posix path conversion in bash
提问by Tomilov Anatoliy
How can I convert a Windowsdir path (say c:/libs/Qt-static) to the correct POSIXdir path (/c/libs/Qt-static) by means of standard msysfeatures? And vice versa?
如何通过标准msys功能将Windows目录路径（例如c:/libs/Qt-static）转换为正确的POSIX目录路径（/c/libs/Qt-static）？反之亦然？

I don't know msys, but a quick google search showed me that it includes the sedutility. So, assuming it works similar in msysthan it does on native Linux, here's one way how to do it:
我不知道msys，但快速的谷歌搜索显示它包含该sed实用程序。因此，假设它的工作方式与msys本机 Linux 上的工作方式相似，这里是一种方法：
From Windows to POSIX
从 Windows 到 POSIX
You'll have to replace all backslashes with slashes, remove the first colon after the drive letter, and add a slash at the beginning:
您必须用斜杠替换所有反斜杠，删除驱动器号后的第一个冒号，并在开头添加一个斜杠：
echo "/$pth" | sed 's/\/\//g' | sed 's/://'
or, as noted by xaizek,
或者，正如 xaizek 所指出的，
echo "/$pth" | sed -e 's/\/\//g' -e 's/://'
From POSIX to Windows
从 POSIX 到 Windows
You'll have to add a semi-colon, remove the first slash and replace all slashes with backslashes:
您必须添加一个分号，删除第一个斜杠并将所有斜杠替换为反斜杠：
echo "$pth" | sed 's/^\///' | sed 's/\//\/g' | sed 's/^./echo "$pth" | sed -e 's/^\///' -e 's/\//\/g' -e 's/^./Output type options:
-d, --dos print DOS (short) form of NAMEs (C:\PROGRA~1\)
-m, --mixed like --windows, but with regular slashes (C:/WINNT)
-M, --mode report on mode of file (binmode or textmode)
-u, --unix (default) print Unix form of NAMEs (/cygdrive/c/winnt)
-w, --windows print Windows form of NAMEs (C:\WINNT)
-t, --type TYPE print TYPE form: 'dos', 'mixed', 'unix', or 'windows'
:/'
:/'
or more efficiently,
或更有效地，
sed '
\,/$, !s,$,/,
\,^/, s,/,:/,2
s,^/,,
s,/,\,g
' <<< "$@"
where $pthis a variable storing the Windows or POSIX path, respectively.
其中$pth是分别存储 Windows 或 POSIX 路径的变量。

Are you using it on cygwin? If yes, then there is a readymade utility called cygpath.exein cygwin package just for doing that.
你在cygwin上使用它吗？如果是，那么cygpath.exe在 cygwin 包中有一个现成的实用程序，专门用于执行此操作。

Here is my implementation (tested on git bash).
这是我的实现（在 git bash 上测试）。
From POSIX to Windows
从 POSIX 到 Windows
/
<path with space>
Works for:
效劳于：
echo "$@" | sed ...
except
除了
$ MSYS_NO_PATHCONV=1 taskkill /F /T /IM ssh-agent.exe
Explanation:
解释：
\,^/, s,/,:/,2(converts /drive/dir/to /drive:/dir/) is the heart of it and inserts :before the 2nd /. I use ,for delim instead of /for readability. If starting with /(\,^/,), then replace /with :/for the 2nd occurrence. I do not want to assume drive letter length of 1 so this works for /sd0/some/dir.
\,^/, s,/,:/,2( 转换/drive/dir/为/drive:/dir/) 是它的核心，并:在2nd之前插入/。我使用,delim 而不是/为了可读性。如果在启动/（\,^/,），然后替换/用:/的2第二发生。我不想假设驱动器号长度为 1，因此这适用于/sd0/some/dir.
s,^/,,removes the leading /and s,/,\\,gconverts all /to \.
s,^/,,删除前导/和s,/,\\,g将所有/到\。
\,/$, !s,$,/,is to handle the corner case of /cand ensure 2nd /(/c/) for the next command to work.
\,/$, !s,$,/,是处理/c2nd /( /c/)的极端情况并确保下一个命令起作用。
Note:
笔记：
If here string <<<does not work in your shell then you can echoand pipe as
如果这里的字符串<<<在你的 shell 中不起作用，那么你可以用echo管道作为

The "correct" way in MSYS is:
MSYS 中的“正确”方式是：
##代码##This avoids having to manually translate slashes. It simply de-activates the path conversion.
这避免了必须手动翻译斜杠。它只是取消激活路径转换。
