PowerShell comparison operators

阅读更多关于 PowerShell comparison operators

问题 PowerShell has a unique set of comparison operators: -eq -gt -lt -ne etc. I vaguely remember using such operators in a different language, but can't recollect which one. Which other languages use such notations? what is reason for not using the standard operators (==, >,<, !=)? 回答1: The Unix test command for instance uses similar operators. Perl has operators like that too, although without the leading hyphen. The reason for PowerShell to use mnemnics rather than symbols for the comparison

Powershell get ipv4 address into a variable

阅读更多关于 Powershell get ipv4 address into a variable

Is there an easy way in powershell 3.0 Windows 7 to get the local computer's ipv4 address into a variable? Lucas Here is another solution: $env:HostIP = ( Get-NetIPConfiguration | Where-Object { $_.IPv4DefaultGateway -ne $null -and $_.NetAdapter.Status -ne "Disconnected" } ).IPv4Address.IPAddress Jana Sattainathan How about this? (not my real IP Address!) PS C:\> $ipV4 = Test-Connection -ComputerName (hostname) -Count 1 | Select IPV4Address PS C:\> $ipV4 IPV4Address ----------- 192.0.2.0 Note that using localhost would just return and IP of 127.0.0.1 PS C:\> $ipV4 = Test-Connection

Example showing how to override TabExpansion2 in Windows PowerShell 3.0

阅读更多关于 Example showing how to override TabExpansion2 in Windows PowerShell 3.0

Does anyone have an example showing how to override the TabExpansion2 function in Windows PowerShell 3.0? I know how to override the old TabExpansion function, but I want to provide a list of items for the intellisense in PowerShell ISE. I looked at the definition of TabExpansion2 and it wasn't easily understandable how I inject my own code in the the tab expansion process. Charlie I think this example should give you a good starting point: Windows Powershell Cookbook: Sample implementation of TabExpansion2 . The example code shows that you can add code both before and after the default calls

I'm using powershell to develop a little tool with graphic interface and I'm going crazy with this issue... For example: I have a label on a form that display "real-time" status of a ping. In the same time, if you click on the label, a popup message is displayed. function GoogleStatus ($Label) { $Google = "www.google.com" If (Test-Connection -ComputerName $Google -Count 1 -Quiet) {Label.Text = "Yes"} else {Label.Text = "No"} } function HelloMsg { [System.Windows.Forms.MessageBox]::Show("Hello","Funny Window",0,32) } [void] [Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

How to queue another TFS (2012) Build from a TFS Build AND pass process parameters?

阅读更多关于 How to queue another TFS (2012) Build from a TFS Build AND pass process parameters?

问题 The product I work on comprises 3/4 seperate (non-dependant) TFS builds. I would like to create a single TFS build which queues the other 3/4 builds from within the ProcessTemplate AND, critically, pass process parameters to them. This build would wait for them all to complete and return an overall success/failure of the build. So my questions are: Can this be achieved by any existing 'standard' Workflow activities (my manager has had bad experiences with custom workflow activities)? If not,

I tried Get-Content , tried some regex from other posts, but I couldn't modify them because I didn't understand it. How could this be done? Graham Gold It's not that clear entirely what you want here - what kind of object and for what purpose? I'll go with an example of what you could do... Say you want to convert that
