powershell-2.0

问题 I am trying to write a script that will look through a set of folders and keep only the last 10 files. The files in each folder could be created daily, weekly or monthly. I need the script to keep the 10 most recent copies regardless of the creation date or modified date. Using another post I created the script below that works but it doesnt keep 10 copies it keeps any file that isn't older than 10 days. $ftppath = "C:\Reports" Get-ChildItem $ftppath -recurse *_Report_*.zip -force|where {$_

问题 I've got a powershell script that monitors a log file, filters out the interesting bits and then presents those bits to me as and when they are written to the file. Works wonderfully. The line of interest is: get-content "$logFile" -wait | where { select-string $searchTerm -inp $_ } Now I want to get fancy! I would like the font colour to change everytime a particular term is encountered. I can set the font colour easily enough, but how would you do it on-the-fly with the above statement?

问题 I am successfully using Powershell with SMO to backup most databases. However, I have several large databases in which I receive a "timeout" error "System.Data.SqlClient.SqlException: Timeout expired". The timout consistently occurs at 10 minutes. I have tried setting ConnectionContext.StatementTimeout to 0, 6000, and to [System.Int32]::MaxValue. The setting made no difference. I have found a number of Google references which indicate setting it to 0 makes it unlimited. No matter what I try,

问题 Does anyone know why Powershell 2.0 is installed in C:\Windows\System32\WindowsPowerShell\v1.0 on a Windows 7 box? 回答1: It's actually an interesting story in side-effects. Visual Studio has a fixed list of assemblies in their "Add Reference" dialog. Anything else has to be browsed for. Developers tended to browse for this location in the Windows directory, where System.Management.Automation.dll (the assembly that runs most of PowerShell lives) This made an absolute reference to this location.

问题 I have the below code that goes through and gets scheduled tasks info and puts the output that occurs on the screen to a log file. However, what I have noticed is that all errors are logged EXCEPT for servers that have "Access is denied" - how can I log those errors in the log file as well.

问题 I want to write a PowerShell script that will recursively search a directory, but exclude specified files (for example, *.log , and myFile.txt ), and also exclude specified directories, and their contents (for example, myDir and all files and folders below myDir ). I have been working with the Get-ChildItem CmdLet, and the Where-Object CmdLet, but I cannot seem to get this exact behavior. 回答1: The Get-ChildItem cmdlet has an -Exclude parameter that is tempting to use but it doesn't work for
