List of all colors available for PowerShell?

阅读更多关于 List of all colors available for PowerShell?

问题 I am searching for a list of all colors I can use in PowerShell. Since we need to provide names and no hexnumbers, it's hard to figure out if a color exists or not, at least if you don't know how :)) For example, as -foregroundcolor write-host "hello world" -foregroundcolor "red" 回答1: The console colors are in an enum called [System.ConsoleColor]. You can list all the values using the GetValues static method of [Enum] [Enum]::GetValues([System.ConsoleColor]) or just [Enum]::GetValues(

Find character position and update file name

问题 What function might I use to find a character position in a string using PowerShell 2.0. i.e I would use CHARINDEX or PATINDEX if using SQL Server. I looked at using the Select-String cmdlet but it doesn't seem to do what I need it to do.

问题 Bit of a simple question but how do I select a specific column in the below code? I only want to show TIME column and nothing else. I try and put in FORMAT_TABLE TIME but it just populates with TIME multiple times without actually showing the time.. $server_event = Get-Content -Path "c:\Temp\Servers.txt" foreach($servers in $server_event) { $event = Get-EventLog -computerName $servers -logname system | Where-Object {$_.EventID -eq 6009} | Select -First 1 $event } RESULT: I ONLY WANT TO SHOW

Powershell - Removing all duplicate entries

阅读更多关于 Powershell - Removing all duplicate entries

I am trying to find a Powershell command line that will read in a text file remove all duplicated lines (2+) and retain none of the duplicated lines. I haven't been able to find an answer for my question anywhere on Stackoverflow nor anywhere else. Every example I have found so far only shows removing one and/or many of the duplicated lines and retaining one. Is this possible through Powershell 2.0? PowerShell Command Example: Get-Content "C:\Temp\OriginalFile.txt" | select -unique| Out-File "C:\Temp\ResultFile.txt" OriginalFile.txt 1 1 1 2 2 3 4 ResultFile.txt (Actual) 1 2 3 4 ResultsFile.txt

Parameters with default value not in PsBoundParameters?

阅读更多关于 Parameters with default value not in PsBoundParameters?

问题 General code Consider this code: PS> function Test { param($p='default value') $PsBoundParameters } PS> Test 'some value' Key Value --- ----- p some value PS> Test # nothing I would expect that $PsBoundParameters would contain record for $p variable on both cases. Is that correct behaviour? Question I'd like to use splatting that would work like this for a lot of functions: function SomeFuncWithManyRequiredParams { param( [Parameter(Mandatory=$true)][string]$p1, [Parameter(Mandatory=$true)]

Powershell argument passing to function seemingly not working

阅读更多关于 Powershell argument passing to function seemingly not working

问题 I sense that I am doing something silly, but here is the issue: Function getPropertyOfFile($a, $b, $c) { $a.GetDetailsOf($b, $c) } If I pass $a, $b, $c variables that are appropriate to the function, it fails saying that "Method invocation failed because [System.Object[]] doesn't contain a method named 'GetDetailsOf'." However, if I directly replace $a, $b, $c with the arguments that I was passing, and then try to run that, it works fine. What the heck is going on? Note: I am using powershell

问题 I am building a small script which should copy all .zip files to a special folder called F:\tempzip . I tried it with Copy-Item cmdlet, but I didn't manage to do it.

Listing files in SharePoint library without SharePoint module via Powershell

阅读更多关于 Listing files in SharePoint library without SharePoint module via Powershell

问题 We have a powershell script running on our Exchange server (Exchange 2010/Win 2008 R2) which needs to query a SharePoint document library in SharePoint 2013 to find a file whose name can be different every day. For example, Stats_2015_10_14_06_00_01.csv or Stats_2015_10_15_06_05_01.csv This precludes me from being able to hardcode the file name and use the System.Net.WebClient method to download the file locally. I also don't have the SharePoint module installed on the Exchange server and of
