In Windows PowerShell, we can use the Get-Content cmdlet to read files from a file. However, the cmdlet will load the entire file contents to memory at once, which will fail or freeze on large files.To solve thi
也可以使用ReadLines的[System.IO.File]方法,它包装了StreamReader,简化了读取过程: PowerShell foreach($linein[System.IO.File]::ReadLines($path)) {if($line.Length-gt10) {$line} } 在大型集合中按属性查找条目 通常需要使用共享属性来标识不同集合中的同一记录,例如使用名称从一个列表中检索 ID,从...
if語句所做的第一件事就是計算括號中的運算式。 如果計算結果為$true,則會在大括號中執行scriptblock。 如果值是$false,則會略過該腳本區塊。 在上一個範例中,if語句只是評估$condition變數。 它是$true,並且會在腳本塊內執行Write-Output命令。 在某些語言中,您可以在if語句後面放置單行程序代碼,並執行它。

事实证明在操作上重定向和Out-File非常的类似:当PowerShell转换管道结果时,文件的内容就像它在控制台上面输出的一样。Set-Content稍微有所不同。它在文件中只列出目录中文件的名称列表,因为在你使用Set-Content时,PowerShell不会自动将对象转换成文本输入。相反,Set-Content会从对象中抽出一个标准属性。上面的情况下,...
Note. Why not? Well, for one thing, it will make your debugging life much easier if your variable names and options correspond. It also makes it quite a bit easier for other people to read – and understand – your script. So what value are we assigning to the variable $yes? Well, ...
