也可以使用[System.IO.File]的ReadLines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,从另一...

I've got a plain text file with two server\instance names in it. The goal is to loop through each one, run some queries, and output the results to Excel files. It actually works as I'd want it to, but also kicks out some errors, as well as an extra excel file named _cfr_0916...

Admins use these resources to configure components, such as registry keys and Windows services, or to create and manage local users through a configuration script. For instance, the File resourcemanages files and folders, the Environment resource manages environment variables and the Registry resource...
The loop also will exit if some maximum number of iterations through the loop is exceeded to prevent an infinite loop condition.Although Windows PowerShell is object-based, it is considered acceptable to refer to simple objects as variables. You can see that the navigateToApp function uses local...
It’s pretty good, except that the file size is reported in bytes, and we’re used to seeing file sizes reported in kilobytes. But hey, short of writing a more complicated script that can loop through all the files in the collection and calculate the size in kilobytes, well, what are ...
looking. By repeatedly passing in the return value from the previous call to FindWindowEx, I effectively advance one window handle on each iteration through the do...while loop inFigure 4. I stop iterating when the local ct variable reaches the value of index, which is passed in as an ...
conditions—such as with a wildcard, regular expression, or even an arbitrary script block. Since scanning through the text in a file is such a common task, PowerShell’sswitchstatement supports that directly. These additions make PowerShellswitchstatements a great deal more powerful than those ...
