排序对象 - 唯一

Question

我正在制作一个脚本，从特定位置收集所有子键并将 REG_BINARY 键转换为文本，但由于某些原因我无法删除重复结果或按字母顺序对它们进行排序。

PS：不幸的是，我需要可以从命令行执行的解决方案。

代码：

$List = ForEach ($i In (Get-ChildItem -Path 'HKCU:SOFTWARE[=10=]0' -Recurse)) {$i.Property | ForEach-Object {([System.Text.Encoding]::Unicode.GetString($i.GetValue($_)))} | Select-String -Pattern ':'}; ForEach ($i In [char[]]'ABCDEFGHIJKLMNOPQRSTUVWXYZ') {$List = $($List -Replace("$i`:", "`n$i`:")).Trim()}; $List | Sort-Object -Unique

Answer 1

经过多次尝试，我发现必须使用Split命令来进行分行，这样才能对结果进行整理。

{$List = ($List -Replace("$i`:", "`n$i`:")) -Split("`n")}

Answer 2

字节数组中编码的路径字符串用 NUL 个字符（代码点 0x0）分隔。

因此，您需要将您的字符串按此字符拆分成一个数组的各个路径，然后您可以对其进行操作比如Sort-Object:

您可以在可扩展的 PowerShell 字符串中将 NUL 字符表示为 "`0"，或者 - 在 regex 中传递给 -split operator - [=17=]:

# Convert the byte array stored in the registry to a string.
$text = [System.Text.Encoding]::Unicode.GetString($i.GetValue($_))

# Split the string into an *array* of strings by NUL.
# Note: -ne '' filters out empty elements (the one at the end, in your case).
$list = $text -split '[=10=]' -ne ''

# Sort the list.
$list | Sort-Object -Unique
