Question

我有一个需要因错误传达而改变的脚本：我们在prod floor上有工作站创建具有以下结构的文件 - 04_R _____“109402”0076_9999992_35_401_“01_20121107”_134029_0667.I00.asd（文件名的引号部分是必须要解析的部分。

我已经使用文件名的第一部分创建了一个数组，并且powershell程序能够解析该数据;但是在文件名的第二部分，必须有一个文件夹结构，由部件号，测试台编号（01,02,03等）创建，然后按日期创建。如果文件夹不存在，则仅在匹配时创建文件夹。

我当前的脚本按前缀过滤（这是错误的）并每天创建所有文件夹（不是匹配）。我想使用子字符串来排除这么多字符以捕获01,02,03等。是否可以不重新创建方向盘并使用我当前的代码进行一些更改？我的所有测试代码都包含在内，任何帮助都会得到极大的赞赏或修改！

Answer 1

你正试图手工完成所有事情。不。

让PowerShell为您完成工作：

$DTS = (Get-Date).FormatDate('yyyy/MM/dd')

$parts_lists = @(
  @("108701"),
  @("108702"),
  @("109401", "1094080", "1094090"),
  @("109402", "1094091", "1094082", "1094092")
)

$destination_dirs = @(
  "\\127.0.0.1\TestFolder1",
  "\\127.0.0.1\TestFolder2",
  "\\127.0.0.1\TestFolder3",
  "\\127.0.0.1\TestFolder4"
)

# The following regular expression defines 2 sub-matches for parts list
# and test bench.
$re = "^\d{2}_[A-Z]___(\d{6})\d{4}_\d{7}_\d{2}_\d{3}_(\d{2})_\d{8}_\d{6}_\d{4}\.[A-Z]\d{2}\.asd$"

Get-ChildItem $source -Recurse | ? { $_.Name -match $re } | % {
  # process only files that match the given regular expression

  # iterate over all 4 parts lists
  for ($i = 0; $i -le 3; $i++) {
    if ( $parts_lists[$i] -contains $matches[1] ) {
      # if the first sub-match (the parts list number) is found in the current
      # parts list, construct a destination path from the corresponding base
      # directory, the test bench number and the date.
      $dest = Join-Path $destination_dirs[$i] -ChildPath "P$($matches[2])\$DTS"

      # Create the destination if it doesn't exist. Creating it here ensures
      # that a destination folder is only created when there's actually a
      # file going into it.
      if ( -not (Test-Path -LiteralPath $dest) ) {
        New-Item -Type Directory $dest
      }

      # Move the file ...
      Move-Item $_.FullName $dest -Force
      # ... end exit from the for-loop (no need to check other parts lists
      # once we found a match).
      break
    }
  }
}

我不确定我是否完全理解你的代码，所以我的示例代码可能需要一些调整，但它应该给你一般的想法。

您需要注意的一件事是日期格式yyyy/MM/dd将使用区域日期分隔符为您提供日期字符串，即在具有美国语言环境的系统上，它将生成日期字符串{{1}而在具有德语语言环境的系统上，日期字符串为2013/02/15。如果希望日期部分用正斜杠分隔（在路径中使用该日期时PowerShell会将其解释为路径分隔符），则需要以格式字符串2013.02.15转义正斜杠。

编辑：正则表达式有两个目的：

将处理限制为仅匹配与模式匹配的文件，
允许访问文件名的部件列表和测试台部分。

模式源自您提供的示例文件名：

04_R ___的 109402 0076_9999992_35_401_的 01_20121107 _134029_0667.I00.asd

yyyy\/MM\/dd：字符串的开头。
^：2位数后跟下划线。
\d{2}_：单个大写字母后跟3个下划线。
[A-Z]___：一组6位数（代表零件清单编号）。稍后可以通过(\d{6})。
$matches[1]：4位数字后跟下划线。
\d{4}_：7位数后跟下划线。
\d{7}_：2位数后跟下划线。
\d{2}_：3位数后跟下划线。
\d{3}_：一组2位数（代表测试台机器编号）后跟下划线。稍后可以通过(\d{2})_。
$matches[2]：8位数（日期）后跟下划线。
\d{8}_：6位数后跟下划线。
\d{6}_：4个数字后跟一个点。
\d{4}\.：单个大写字母后跟2位数字。
[A-Z]\d{2}：单个点后跟小写字母\.asd，a和s（扩展名）。
d：字符串的结尾。
