我编写了一个脚本来创建一系列符号链接。我想将目标值设置为 $shortpath 其中
$shortpath = "%userprofile%\dir1\dir2\dir3\filename.ext"
$shortpath 变量的值是有效的,我可以从运行命令打开它。PS 在创建符号链接时尝试写入的字符串与预期的不同。我希望它会写入字符串的值,或者至少插入 Env 变量的值。而是添加到我传递给它的字符串中。
New-Item -Path $currpath -ItemType SymbolicLink -Value ($targetpath) -Force
我希望目标值为: c:\Users\UserName\dir1\dir2\dir3\filename.ext 或 %userprofile%\dir1\dir2\dir3\filename.ext
相反,我得到: C:\windows\system32%UserProfile$\dir1\dir2\dir3\filename.ext
写入日志文件的输出示例:
wholepath = C:\Users\UserName\dir1\dir2\dir3\longfilename1.ext
spath = C:\Users\UserName\dir1\dir2\dir3\longfi~1.ext
envpath = C:\Users\UserName\
midpart = dir1\dir2\dir3\
filename = longfi~1.ext
targetpath = %UserProfile%\dir1\dir2\dir3\longfi~1.ext
谁能阐明为什么会发生这种情况?如果我使用 mklink,也会发生同样的事情。我在下面添加了整个脚本:
function Get-ShortPathName
{
Param([string] $path)
$MethodDefinition = @'
[DllImport("kernel32.dll", CharSet = CharSet.Unicode, EntryPoint = "GetShortPathNameW", SetLastError = true)]
public static extern int GetShortPathName(string pathName, System.Text.StringBuilder shortName, int cbShortName);
'@
$Kernel32 = Add-Type -MemberDefinition $MethodDefinition -Name 'Kernel32' -Namespace 'Win32' -PassThru
$shortPath = New-Object System.Text.StringBuilder(500)
$retVal = $Kernel32::GetShortPathName($path, $shortPath, $shortPath.Capacity)
return $shortPath.ToString()
}

$dest = "C:\SwSetup\asdfg\"
$src = $src.Replace("\","\\")

$i = Get-ChildItem -LiteralPath $src -Recurse

$i | ForEach-Object {

$apath = $_.FullName -Replace $src,""
$cpath = $dest + $apath

If(!(Test-Path (Split-Path -Parent $cpath))){
New-Item -ItemType Directory -Force -Path (Split-Path -Parent $cpath)
}

$wholepath = ([WildcardPattern]::Escape($_.FullName))
$shortPath = Get-ShortPathName($wholepath)
$envpath = $shortpath.substring(0,18)

$filename = Split-Path $shortpath -leaf
