I am writing a script to use multiple plink (PuTTY) sessions as a Windows version of clusterssh. I am stuck however because I want to open multiple Powershell windows from powershell.

阅读更多关于 Powershell/C#: Invoking a pipeline asynchronously & displaying the results

As per this sample - http://msdn.microsoft.com/en-us/library/windows/desktop/ee706590(v=vs.85).aspx , I am trying to invoke my script in an async way. But, at the same time, I want to give feedback to the GUI on the set of operations happening i.e. want to spit the Write-verbose stuffs happening behind the scenes parallely on the GUI. I am confused in achieving this - because I see there is a DataReady event on the PipelineReader object ? Is it possible to somehow consume that w.r.t the MSDN sample above such that I can show feedback on the GUI ? Conceptually, I am not able to relate this

pipes and foreach loops

阅读更多关于 pipes and foreach loops

Recently, I've been playing with PowerShell, and I've noticed some weird behavior when using pipes and foreach loops that I couldn't understand. This simple code works: $x = foreach ($i in gci){$i.length} $x | measure -max Makes sense. But this code won't: foreach ($i in gci){$i.length} | measure -max And I'm getting the following error: An empty pipe element is not allowed. At line:1 char:33 + foreach ($i in gci){$i.length} | <<<< measure -max + CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : EmptyPipeElement What is the difference between

Renaming Files with PowerShell

阅读更多关于 Renaming Files with PowerShell

I need to rename a bunch of files at once in Windows PowerShell. I read the HTG article here and it helped a little. My problem is that It will only rename files in the top of the directory, nothing deeper. For example: There is FOLDER A and inside FOLDERA is a document and FOLDER B. Inside FOLDER B is another document. Both folders and both documents need to be renamed. The way it is working now is that FOLDER A, the document in FOLDER A, and FOLDER B are being renamed, but not the document inside FOLDER B. My current code is: Dir | Rename-Item –NewName { $_.name –replace “ “,”_” } Thanks for
