  T80219A CC  Unspecified infection due to central venous catheter, initial encounter

我开始使用一些代码

$filename = "HAC.txt"
$output_file = "extract_$HAC06"

$extract = @()
select-string -path $filename -pattern "HAC" -context 0,1 |
    foreach-object {
    $extract += $_.line
    $extract += $_.context.postcontext
    }

$extract | out-file $output_file

但是我被困......任何帮助

您可以将所有文本导入为一个多行字符串，将其拆分为HAC行，然后根据第一行中列出的HAC编号导出每个文本。像这样：

$AllText = (Get-Content "HAC.txt") -join "`r`n"
$AllText -Split "(?=HAC \d)"| Where{$_ -match "^(HAC \d+)"} | ForEach{Set-Content -Value $_ -Path ($Matches[1]+'.txt')}

这将输出3个以HAC代码命名的文件，其中包含您正在寻找的内容。

编辑：好的，如果您想要修改文件的输出位置，我们可以添加如下路径：

$OutFolder = 'C:\Path\For\Output\'
$AllText = (Get-Content "HAC.txt") -join "`r`n"
$AllText -Split "(?=HAC \d)"| Where{$_ -match "^(HAC \d+)"} | ForEach{Set-Content -Value $_ -Path ($OutFolder + $Matches[1] + '.txt')}

Powershell脚本用于在关键字之间提取文本
