在 Powershell 5.0 中每次函数为运行时增加一个数字一次

Question

我只是在寻找一种方法，每当它下面的脚本是运行时，它就会递增变量 $Num。所以脚本从使用 168 开始，运行，然后增加到 169，再次运行，直到 999。谢谢！

$Path = "H:\ClientFiles\CHS\Processed\"
$Num = 168
$ZipFile = "FileGroup0000000$Num.zip"
$File = "*$Num*.83*"
$n = dir -Path $Path$File | Measure

        if($n.count -gt 0){
        Remove-Item $Path$ZipFile
        Compress-Archive -Path $Path$File -DestinationPath $Path
        Rename-Item $Path'.zip' $Path'FileGroup0000000'$Num'.zip'          
        Remove-Item $Path$File            

        }    
        else {
            Write-Output "No Files to Move for FileGroup$File"
        }

这就是 for 循环的本质！

$Path = "H:\ClientFiles\CHS\Processed\"
for($Num = 168; $Num -le 999; $Num++){
    $ZipFile = "FileGroup0000000$Num.zip"
    $File = "*$Num*.83*"
    $n = dir -Path $Path$File | Measure

    if ($n.count -gt 0) {
        Remove-Item $Path$ZipFile
        Compress-Archive -Path $Path$File -DestinationPath $Path
        Rename-Item "${Path}.zip" "${Path}FileGroup0000000${Num}.zip"
        Remove-Item $Path$File

    }
    else {
        Write-Output "No Files to Move for FileGroup$File"
    }
}

我们的 for() 循环声明的分解：

for($Num = 168; $Num -le 999; $Num++){
 #       ^            ^          ^
 #       |            |          | Increase by one every time
 #       |            | Keep running as long as $num is less than or equal to 999
 #       | Start with an initial value of 168
}

不确定你想走这条路。您可以拥有一个维护脚本变量的模块：

# file.psm1

$script:num = 1

function myfunc {
  $script:num
  $script:num++
}

import-module .\file.psm1

myfunc
1

myfunc
2

myfunc
3

remove-module file

我正在回答post的标题。您的模块看起来像这样，但 powershell 提示符必须始终打开。

$num = $script:Num = 168

function myfunc { 
  $Path = ".\"
  $ZipFile = "FileGroup0000000$Num.zip"
  $File = "*$Num*.83*"
  $n = dir -Path $Path$File | Measure

  if($n.count -gt 0){
    Remove-Item $Path$ZipFile
    Compress-Archive -Path $Path$File -DestinationPath $Path
    Rename-Item $Path'.zip' $Path'FileGroup0000000'$Num'.zip'          
    Remove-Item $Path$File            
  } else {
    Write-Output "No Files to Move for FileGroup$File"
  }

  $script:num++
}
