解析文件名，创建文件夹结构

2013-02-14 126 views

由于沟通不畅，我有一个需要更改的脚本：我们在产品层上创建了具有以下结构的文件的工作站 - 04_R ______“109402”0076_9999992_35_401_“01_20121107”_134029_0667.I00。 asd（文件名的引号部分是必须解析的部分）解析文件名，创建文件夹结构

我已经创建了一个包含文件名第一部分的数组，并且powershell程序能够解析该数据;但是，文件名的第二部分必须有由零件编号，测试平台编号（01,02,03等），然后按日期创建的文件夹结构。如果文件夹不存在，则仅当存在匹配时才创建文件夹。

我的当前脚本按前缀进行过滤（这是错误的）并每天创建所有文件夹（不匹配）。我想使用一个子串来排除如此多的字符来捕获01,02,03等。有没有可能不重新创建轮子并使用我的当前代码进行一些更改？我所有的测试代码都包含在内，任何帮助都将得到极大的认可或修改！

你正在试图做手工一切。别。

让PowerShell中做的工作适合你：

$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 
    } 
    } 
}

我不知道如果我完全理解你的代码，所以我的示例代码可能需要一些调整，但它应该给你的总体思路。你需要知道的

一件事是，日期格式yyyy/MM/dd将使用区域日期分隔符，即在系统与美国的区域会产生一个日期字符串2013/02/15而在与德国系统，给你一个日期字符串日期字符串的区域设置为2013.02.15。如果您希望日期部分由正斜杠分隔（当您在路径中使用该日期时，PowerShell将解释为路径分隔符），则需要在格式字符串中转义正斜杠：yyyy\/MM\/dd。

编辑：正则表达式有2个目的：

  • 限制处理以仅那些该模式匹配的文件，并且
  • 授予访问权限的零件清单和测试台部件文件名。

的模式是从你给的例子文件名派生：

04_R___ 0076_9999992_35_401_ 01_20121107 _134029_0667.I00。ASD

  • ^：字符串的开头。
  • \d{2}_：2位数后跟下划线。
  • [A-Z]___：单个大写字母后跟3个下划线。
  • (\d{6})：一组6位数字（表示零件清单号码）。该组可以稍后通过$matches[1]访问。
  • \d{4}_：4位数字后跟下划线。
  • \d{7}_：7位数字后跟下划线。
  • \d{2}_：2位数后跟下划线。
  • \d{3}_：3位数字后跟下划线。
  • (\d{2})_：一组2位数字（代表测试台机器编号）后跟下划线。该组可以稍后通过$matches[2]访问。
  • \d{8}_：8位数字（日期）后跟下划线。
  • \d{6}_：6位数字后跟下划线。
  • \d{4}\.：4位数字后跟一个点。
  • [A-Z]\d{2}：一个大写字母后跟2个数字。
  • \.asd：单点后跟小写字母a，s和d（扩展名）。
  • $：字符串的结尾。

Ansgar - 你能否用正则表达式来帮助：$ re =“^ \ d {2} _ [AZ] ___（\ d {6}）\ d {4} _ \ d {7} _ \ d {2} _ \ d {3} _（\ d {2}）_ \ d {8} _ \ d {6} _ \ d {4}。[AZ] \ d {2} \。asd $“我对这段代码进行了总体分析，因为我对.NET不是很熟悉.net再次感谢您的帮助！ – user1801422 2013-02-20 18:27:45
