Question

我从@Kieranties找到了以下代码，对我来说非常有效，除了我的输入文件的第一行中没有日期。

输出文件不输入日期（没关系），也不在第一行中输入管道定界符。其他所有行都是完美的。

我很幸运地尝试修改此代码。

Function Parse-CDRFileLine {
    Param(
        [string]$line
    )

    $pattern = "^(.{2})(.{2})(.{1})(.{2})(.{1})(.{1})\s*(.{15})(.{10})\s*(.{7})\s*(.{7})\s*(.{1})\s*(.{1})(.{1})(.{1})\s*(.*)$"
    if($line -match $pattern){ 
        $result = $matches.Values | select -first ($matches.Count-1)
        [array]::Reverse($result, 0, $result.Length)
        $result = $result -join "|"    
        $result
    }
}



Function Parse-CDRFile{
    Param(
        [string]$filepath
    )    

    # Read content, setting first line to $date, the rest to $content
    $date,$content = Get-Content $filepath    

    # Create the output file, overwrite if neccessary
    $outputFile = New-Item "$filepath.out" -ItemType file -Force

    # Add the date line
    Set-Content $outputFile $date

    # Process the rest of the content
    $content | 
        ? { -not([string]::IsNullOrEmpty($_)) } |
        % { Add-Content $outputFile (Parse-CDRFileLine $_) }
}

Parse-CDRFile "C:\input.txt"

我能够弄清楚。我必须从读取$ date，$ content = Get-Content $ filepath的行中删除“ $ date”，然后完全删除该行。设置内容$ outputFile $ date

最终代码是

Function Parse-CDRFileLine {
    Param(
        [string]$line
    )

    $pattern = "^(.{2})(.{2})(.{1})(.{2})(.{1})(.{1})\s*(.{15})(.{10})\s*(.{7})\s*(.{7})\s*(.{1})\s*(.{1})(.{1})(.{1})\s*(.*)$"
    if($line -match $pattern){ 
        $result = $matches.Values | select -first ($matches.Count-1)
        [array]::Reverse($result, 0, $result.Length)
        $result = $result -join "|"    
        $result
    }
}



Function Parse-CDRFile{
    Param(
        [string]$filepath
    )    

    # Read content, setting first line to $date, the rest to $content
    $content = Get-Content $filepath    

    # Create the output file, overwrite if neccessary
    $outputFile = New-Item "$filepath.out" -ItemType file -Force


    # Process the rest of the content
    $content | 
        Where { -not([string]::IsNullOrEmpty($_)) } |
        Foreach { Add-Content $outputFile (Parse-CDRFileLine $_) }
}

Parse-CDRFile "C:\input.txt"

使用PowerShell读取文件并在输出文件中插入定界符
