如何在 Windows 上自动查找损坏的符号链接？

  • 772

不确定这是否是糟糕的风格，但我在这里问这个问题是因为我在别处找不到答案，然后我自己制定了一个解决方案。我很想看看其他人的解决方案，但几天后我会发布自己的解决方案。

在我的具体情况下，我在 Windows 7 上运行，但我对其他/旧版本 Windows 的答案感兴趣。我意识到一个答案是“安装一个 Unix 版本，然后解决 Unix ”，但我想要一个更“本地”的解决方案。

编辑 2012-07-17：澄清：“自动”我理想的意思是我可以作为脚本的一部分运行，而不是一个 GUI 工具，它可以在按下按钮时完成所有工作，因为我想做这个无人值守。

windows symbolic-link

    有点迟了，但这是我自己对我的问题的回答。它基本上与 Unix 上常用的方法相同：找到所有链接，然后对损坏的链接采取行动；它只是不那么简洁。下面的脚本在转储了一些关于它们的信息后删除了损坏的符号链接。

    @echo off

rem Grab the list of directories to scan, before we "pushd to dir containing this script",
rem so that we can have the default be "dir from which we ran this script".
setlocal
if x%CD%==x (echo Command Extensions must be enabled. && goto :eof)
set ORIGINAL_DIR=%CD%

pushd %~dp0

set DIRS_TO_CHECK=%*
if x%DIRS_TO_CHECK%==x (
    set DIRS_TO_CHECK=.
)

rem Find all the files which are both links (/al) and directories (/ad).
rem (We use "delims=" in case any paths have a space; space is a delim by default.)
rem If not, delete it (and assume something else will fix it later :-).
echo Deleting broken symlinks ...
echo.
for %%D in (%ORIGINAL_DIR%\%DIRS_TO_CHECK%) do (
    echo Checking %%D
    echo.
    pushd %%D
    if errorlevel 1 (
        echo Cannot find "%%D"
        echo.
        goto :Next_Dir
    )
    rem Clean up broken directory links.
    for /f "usebackq delims=" %%L in (`dir /adl /b`) do (
        rem Check the directory link works.
        rem Redirecting to nul just to hide "The system cannot find the file specified." message.
        pushd "%%L" >nul 2>&1
        if errorlevel 1 (
            echo Deleting broken directory symlink "%%L".
            rem First dump out some info on the link, before we delete it.
            rem I'd rather a more human-readable form, but don't know how to get that.
            fsutil reparsepoint query "%%L"
            rmdir "%%L"
            echo.
        ) else (
            popd
        )
    )
    rem Clean up broken file (non-directory) links.
    for /f "usebackq delims=" %%L in (`dir /a-dl /b`) do (
        rem Check the file link works.
        rem Redirecting to nul just to hide "The system cannot find the file specified." message.
        copy "%%L" nul >nul 2>&1
        if errorlevel 1 (
            echo Deleting broken file symlink "%%L".
            rem First dump out some info on the link, before we delete it.
            rem I'd rather a more human-readable form, but don't know how to get that.
            fsutil reparsepoint query "%%L"
            rm "%%L"
            echo.
        ) else (
            popd
        )
    )
    popd
    :Next_Dir
    rem Putting a label on the line immediately before a ')' causes a batch file parse error, hence this comment.
)
echo Deleting broken symlinks ... done.

:Finally
popd

  2. 以下工具可以帮助您在 Windows 中查找和删除符号链接

    1. 连接链路魔法
    2. 磁盘连接

  3. 您还可以尝试一个名为SageLinks的开源实用程序，它显示并检查 Windows NTFS 连接、符号链接甚至快捷方式。

  4. 使用 cygwin64 (find, xargs, sh, ls)（在 win7 上测试死的 ntfs 硬链接）

    c:\>   find ./ -type l |  xargs -I % sh -c "ls % > /dev/null 2>&1 || echo %"

    注意：test -e 不能像预期的那样使用死的 ntfs 硬链接。
