Question

我刚刚开始学习powershell脚本，我遇到了一个我无法弄清楚的问题。我有很多.sql文件。我需要将其文件名插入文件的开头（在USE语句之后）和文件的结尾（在最后一个END语句之前）。有人知道怎么做吗？

非常感谢

问候

Answer 1

There are a few ways to do that.
Here is the one I would use:
1.  Load up a list of your files using get-item
2.  loop through those files 
3.  for each file, load the sql file into a variable using get-content: $d = get-content -path $yourfilename
4.  then add your data at the beginning and end
5.  $beg = @'
stuff at the beginning
'@
6.  $end = @'
stuff at the end
'@
7.  $d = $beg + $d + $end
8.  use set-content to write the file back

像这样的东西。远非傻瓜证明，需要检查和填充，可能以更优雅的方式编写，但为您提供整体想法。

param (
    [string] $testFile = "testfile.sql",
    [string] $result = "testfilemodified.sql"
)

$fileContent = Get-Content $testFile
$lineCount = $fileContent.Count
$count = $lineCount

$fileContent | %{

    $line = $_
    $count--

    $line | Out-File $result -Append

    if ($line.Contains("use"))
        { "-- $testFile" | Out-File $result -Append; }

    if ($count -eq 1)
        {  "-- $testFile" | Out-File $result -Append; }
}
