I need to be able to find a NIC by IP address, whether full or partial. So writing something like:
Get-NIC-By-IP 10.10.*
Could return:
Ethernet
I know how to do this in Bash but haven't been able to find a PowerShell solution to this.
For versions of Windows and/or PowerShell that do not support Get-NetIPAddress, you can get the requisite information with a combination of the WMI queries for the classes Win32_NetworkAdapterConfiguration and Win32_NetworkAdapter:
$Configs = Get-WMIObject -Class Win32_NetworkAdapterConfiguration -Filter "IPEnabled='TRUE'" | Where-Object {$_.IPAddress -like "192.168.*"}
ForEach ($Config in $Configs) {
Get-WMIObject -Class Win32_NetworkAdapter -Filter "Index=$($Config.Index)" | Select-Object NetConnectionID,Description
}
By using the following command you will receive every interface which matches the IP-addres which you mention in the match clause.
Get-NetIPAddress | ?{ $_.AddressFamily -eq "IPv4" -and ($_.IPAddress -match "192.")} | Select-Object InterfaceAlias
In my case this is:
InterfaceAlias
--------------
Ethernet 2
Ethernet
Of course, you can modify the output if necessary.
Supplement for old OS'es
You can't run this script on old Windows browsers as the cmdlet isn't included according to this thread on TechNet: https://social.technet.microsoft.com/Forums/office/en-US/dcc966a1-24c2-4ae4-b39d-b78df52b6aef/install-of-powershell-3-on-windows-7-seems-to-be-missing-modules?forum=winserverpowershell
There are many cmdlets in Powershell for Windows 8 and Server 2012 (PS V3) that are not included in the V3 release for Windows 7. An example would be Get-NetIPAddress, and many other network-related cmdlets.
Then again, it might be a good idea to upgrade the OS to a supported version (if possible of course).

I am using PS V3.0 to check Google chrome version:
get-content -Path C:\Support\assets.txt | ForEach-Object ({get-wmiobject win32_product -ComputerName $_ | where-Object {$_.name -eq "google chrome"} |FT version})
{write-host "$_"}
Inside the txt file are the IP addresses of remote devices.
The command is working fine and gives me Chrome version, but I cannot include IP address inside the loop.
It gives me only chrome version without information to which remote device it's from. I would like to get something like this :
IP address - Chrome version
IP address - Chrome version
As far as I understand this it should be Foreach (action){do something}?
Also is there any chance to remove word "version" from the input?
Ok, you've made some very innocent beginner type mistakes, but that's fairly easily remedied.
Let's start with ft. ft is short for Format-Table. Generally speaking, you only use a Format- command when you are trying to output something. You are trying to use the results of that, not output it, so we need to drop the ft. Instead use the Select-Object cmdlet (or more commonly used is the shorter select).
get-content -Path C:\Support\assets.txt | ForEach-Object ({get-wmiobject win32_product -ComputerName $_ | where-Object {$_.name -eq "google chrome"} |Select version})
Ok, that gets you an array of objects that only have the Version property. Not super useful, especially when you wanted to know what computer each is associated with! So, that's a good lesson in general, but not very practical here. Let's move on with actually making things better!
You are making things harder than need be by piping things to a ForEach loop like that. You are making separate Get-WMIObject calls against each IP address. If we look at get-help get-wmiobject -parameter computername we can see that it accepts an array of strings. So we can make 1 call against multiple targets, which should help speed things up a bit.
$IPList = get-content -Path C:\Support\assets.txt
Get-WMIObject win32_product -ComputerName $IPList | Where{$_.Name -eq 'Google Chrome'}
That should speed up your results a bit, but what will make things a whole lot faster is to use Get-WMIObject's -Filter parameter instead of Where. The reason is that the provider is more efficient at filtering its own objects, and returning just what you want, than PowerShell is as filtering things. Also, this reduces the data sent back from the remote machines, so you are only getting the data you want from them rather than potentially hundreds of results per machine, and then parsing down to just the ones you want. Essentially you have all of the computers' processors working on your problem, instead of just yours. So let's use the -Filter parameter:
$IPList = get-content -Path C:\Support\assets.txt
Get-WMIObject win32_product -ComputerName $IPList -Filter "Name='Google Chrome'"
Ok, things should come back a whole lot faster now. So down to the last item, you want the computer name for what each version was found on. Good news, you already have it! Well, we have the actual name of the computer, not the IP address that you specified. It is not displayed by default, but each one of those results has a PSComputerName property that you can refer to. We can simply pipe to Select and specify the properties that we want:
$IPList = get-content -Path C:\Support\assets.txt
Get-WMIObject win32_product -ComputerName $IPList -Filter "Name='Google Chrome'" | Select PSComputerName,Version
That's probably going to get you results that you're happy with. If not, you can run it through a ForEach loop similarly to how you were, and format it like you specified:
$IPList = get-content -Path C:\Support\assets.txt
ForEach($IP in $IPList){
$Version = Get-WMIObject win32_product -ComputerName $IP -Filter "Name='Google Chrome'" | Select -Expand Version
"$IP - $Version"
}
If a computer has multiple gateways, how can I determine which is the default gateway using the PowerShell?
If you're on PowerShell v3, you can use Get-NetIPConfiguration e.g.:
Get-NetIPConfiguration | Foreach IPv4DefaultGateway
I think this will be more cross platform:
Get-NetRoute |
where {$_.DestinationPrefix -eq '0.0.0.0/0'} |
select { $_.NextHop }
You need to know which of the multiple gateways are used? If so. From what I remember, when multiple gateways are available the gateway with the lowest metric("cost" based on link speed) is used. To get this, run the following command:
Get-WmiObject -Class Win32_IP4RouteTable |
where { $_.destination -eq '0.0.0.0' -and $_.mask -eq '0.0.0.0'} |
Sort-Object metric1 | select nexthop, metric1, interfaceindex
if there are multiple default gateways with the same cost, I think it's decided using the binding order of the network adapters. The only way I know to get this is using GUI and registry. To include binding order you could save the output of the script over, get the settingsid from Win32_networkadapterconfiguration (identify using interfaceindex), and read the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Linkage\Bind. This key lists the binding order it seems, and the settingsid you get from win32_networkadapterconfiguration is the GUID they identify the device with. Then sort the gateways with equal metrics using their order in the Bind reg.key and you got your answer.

I found it as the below which lists all active gateways, correct me if I am wrong
(Get-wmiObject Win32_networkAdapterConfiguration | ?{$_.IPEnabled}).DefaultIPGateway
Use the WMI queries to pull the data that you're looking for. Below is a fairly simple example to pull the default gateway for a device specified in the first line variable. This will query the device for network adapters and display the found information (for each adapter) to the console window - pulls adapter index, adapter description, and default gateway
Shouldn't take much to expand this to process multiple devices, or process based on a list fed via an input file.
$computer = $env:COMPUTERNAME
Get-WmiObject win32_networkAdapterConfiguration -ComputerName $computer |
Select index,description,defaultipgateway |
Format-Table -AutoSize
$ActiveNet = Get-NetAdapter –Physical |Where-Object {$_.status -eq "Up"} | select name
$Network = Get-NetIPAddress |Where-Object EnabledDefault -EQ 2 | Where-Object InterfaceAlias -EQ $ActiveNet.name | Where-Object IPv4Address -NE $null | select *
$DefautGateway = Get-NetRoute -InterfaceIndex $Network.InterfaceIndex -DestinationPrefix "0.0.0.0/0" | select NextHop
$DefautGateway.NextHop
I am new to PowerShell and I am trying to write a script that will install a series of network printers for me. To get me started I was looking for a way to find all shared printers on a print server and then install them locally. Here is something that doesn't work but gets the idea across. One thing to note is that this is this script is being run on a win 2008 server.
Get-WmiObject -computername $printServer -class Win32_Printer | Where {$_.name -notlike "Microsoft*"} | add-printer -connectionname \\$_.systemName\$_.shareName
I don't currently have a way to test this but I believe that this may work for you.
$printClass = [wmiclass]"win32_printer"
Get-WmiObject -computername $printServer -class Win32_Printer | ? {$_.name -notlike "Microsoft*"} | % { $printClass.AddPrinterConnection([string]::Concat("\\", $_.systemName, "\", $_.shareName)) }

I did this in the past, and can't remember the correct command (I think I was using instring or soemthign?)
I want to list all the windows services running that have the word 'sql' in them.
Listing all the windows services is:
Get-Service
Is there a instring function that does this?
Get-Service -Name *sql*
A longer alternative would be:
Get-Service | where-object {$_.name -like '*sql*'}
Many cmdlets offer built in filtering and support wildcards. If you check the help files (Get-Help Get-Service -full), you will see
-name <string[]>
Specifies the service names of services to be retrieved. Wildcards are
permitted. By default, Get-Service gets all of the services on the comp
uter.
Required? false
Position? 1
Default value *
Accept pipeline input? true (ByValue, ByPropertyName)
Accept wildcard characters? true
Usually if filtering is built in to the cmdlet, that is the preferred way to go, since it is often faster and more efficient.
In this case, there might not be too much of a performance benefit, but in V2, where you could be pulling services from a remote computer and filtering there would be the preferred method (less data to send back to the calling computer).
You can get all the services that are running and having words sql.
Get-Service | Where-Object {$_.Status -eq "Running"} | Where-Object {$_.Name -like "*sql*"}
If you want more information, see this (not much difference)

Hope it helps...
Please enter below command:
Get-Service -Name '*<search string>*'
Above answers are great, but this is more useful:
Get-WmiObject -ComputerName <INSERT COMPUTER NAME> -Class Win32_Service | where-object {$_.name -like '*sql*'}
It allows for this query on remote computers.
The Search String might be in either Display Name or Service Name (e.g. searching Service Name for "*SQL*" does not include the SQL Integration Services ...) so I filter both:
get-service | Where-Object {$_.DisplayName -like "*MySearchString*" -or $_.ServiceName -like "*MySearchString*"}
