I would like to generate Bytes per cluster and Bytes per File record segment data for over 50 servers into an excel sheet (for a drive D)
I know the command "Fsutil fsinfo ntfsinfo [drive letter:]" provides this info but only for local system.
i tried writing this but it did not work.
"Enter-PSSession Server1
Fsutil fsinfo ntfsinfo D:
Exit-PSSession"
I then executed each command manually and it was working.
Can anyone please help me create a script to get the above mentioned data at one go for 50 servers.
Thank you
Continuing from my comment, you can use cmdlet Invoke-Comand for that:
# you may already have admin permissions on each of the servers, but if not, get craedentials for someone that has
$adminCreds = Get-Credential -Message 'Please add your admin credentials to get server information'
# your list of server names here
$servers = 'Server01', 'Server02' # etc.
# next use 'Invoke-Command' to have each server run the code
$result = Invoke-Command -ComputerName $servers -Credential $adminCreds -ScriptBlock {
# have each server run the Fsutil command, and return that as PsCustomObject for convenience
# instead of an array of lines.
# to use ConvertFrom-StringData in PowerShell < 7.x, you need to replace the first colon with a equals sign
# PowerShell versions above 5.1 can use parameter -Delimiter '='
[PsCustomObject]((Fsutil fsinfo ntfsinfo D:) -replace '(?<!:.*):', '=' -join "`r`n" | ConvertFrom-StringData)
}
Now you can save the entire result to CSV or limit to the properties you need like
$result | Select-Object PSComputerName, 'Bytes Per Cluster', 'Bytes Per FileRecord Segment' | Export-Csv -Path 'X:\serverInfo.csv' -NoTypeInformation
If you are not sure all of the servers can be reached, do a loop:
$result = foreach ($server in $servers) {
# test if the server can be reached
if (Test-Connection -ComputerName $server -Count 1 -Quiet) {
Invoke-Command -ComputerName $server -Credential $adminCreds -ScriptBlock {
# have each server run the Fsutil command, and return that as PsCustomObject for convenience
# instead of an array of lines.
# to use ConvertFrom-StringData in PowerShell < 7.x, you need to replace the first colon with a equals sign
# PowerShell versions above 5.1 can use parameter -Delimiter '='
[PsCustomObject]((Fsutil fsinfo ntfsinfo D:) -replace '(?<!:.*):', '=' -join "`r`n" | ConvertFrom-StringData)
}
}
else {
Write-Warning "Server $server is off-line!"
}
}

I'm trying to write up a script which would find (and later add reservation) for DHCP device. The problem I'm having that there is one scope, and within this scope we manually divided into different IP ranges where certain type of devices should be added.
E.g. the scope 10.92.0.0/24 and we assign ranges as
10.92.0.10-20 for iPhones etc.
10.92.0.10.50 for Android phones etc.
I've got the point where the script can go through the IP ranges I provide to it, and either GET DHCP reservation or show error. I've been thinking that first Error could be taken as the free IP.
Any ideas anyone? :)
# Get DHCP Scope
$Start = 100
$End = 140
$DHCPServer = "dhcpserver.company.com"
# Find Free IP address
#It can use to get DHCP reservation by IP and find the one which returns error - which can be used as the free one - loop done
#Now how to tell it to stop when the error occures?
While ($Start -le $End) {
$IP = "10.92.0.$Start"
Write-Host "Reservation for: $IP" -ForegroundColor Cyan
Get-DhcpServerv4Reservation -ComputerName $DHCPServer -IPAddress $IP
$Start++
}
Why don't you use the dedicated cmdlet Get-DhcpServerv4FreeIPAddress?
Get-DhcpServerv4FreeIPAddress -ScopeId "192.168.1.0" -StartAddress "192.168.1.100" -EndAddress "192.168.1.140" -ComputerName "dhcpserver.company.com"
You can assign the output of Get-DhcpServerv4Reservation to a variable, then act on that:
While ($Start -le $End) {
$IP = "10.92.0.$Start"
$reservation = Get-DhcpServerv4Reservation -ComputerName $DHCPServer -IPAddress $IP -ErrorAction SilentlyContinue
if($reservation){
Write-Host "Reservation for: $IP" -ForegroundColor Cyan
$reservation
}
else {
Write-Host "No reservation found for: $IP" -ForegroundColor Red
break #comment out to continue through all IPs in Scope
}
$Start++
}
I have 100+ servers for which I have to check services. On almost 5 servers we have identical services. Each boxes contains min of 3 services.
I am importing content from the file I saved in a location. For Server name I am good. For Service I have saved like service_starting_name* in column under the file like below
AA*
BB*
CC*
Below is the code. Is this good idea for automation as per below code ?
$ServerName = Get-Content "Absolutepath"
$Service = Get-Content "Absolutepath"
foreach ($Server in $ServerName) {
write-host $($server)
Get-Service -ComputerName $Server $Service
}
Also , How can we do a better display like, without printing the service name ?
Suppose, In Server X , 5 services , so if all services are running just print all good on that server.
I tried using if conditions but as there are many services , it is printing multiple times because for for each loop .
Please suggest.
You can play around with various things..
For testing I use localhost, when you try:
Get-Service -ComputerName localhost -DisplayName *sophos*
You get:
(Get-Service -ComputerName localhost -DisplayName *sophos*).count
result 10
(Get-Service -ComputerName localhost -DisplayName *sophos*).Status -contains "stopped"
result True
So if you use:
if (!((Get-Service -ComputerName localhost -DisplayName *sophos*).Status -contains stopped)) { Write-Host "Localhost: All ok" }
Or:
if (!(Get-Service -ComputerName $server -DisplayName $Service | select status | where {$_.Status -like "Stopped"})) { Write-Host "$($Server): All OK" }
You can use various checks for services "stopping" or whatever..
The above are just to give you ideas!
Hope it helps.
Is there an easy way in PowerShell 3.0 on Windows 7 to get the local computer's IPv4 address into a variable?
Here is another solution:
$env:HostIP = (
Get-NetIPConfiguration |
Where-Object {
$_.IPv4DefaultGateway -ne $null -and
$_.NetAdapter.Status -ne "Disconnected"
}
).IPv4Address.IPAddress
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 -ComputerName localhost -Count 1 | Select IPV4Address
PS C:\> $ipV4
IPV4Address
-----------
127.0.0.1
The IP Address object has to be expanded out to get the address string
PS C:\> $ipV4 = Test-Connection -ComputerName (hostname) -Count 1 | Select -ExpandProperty IPV4Address
PS C:\> $ipV4
Address : 556228818
AddressFamily : InterNetwork
ScopeId :
IsIPv6Multicast : False
IsIPv6LinkLocal : False
IsIPv6SiteLocal : False
IsIPv6Teredo : False
IsIPv4MappedToIPv6 : False
IPAddressToString : 192.0.2.0
PS C:\> $ipV4.IPAddressToString
192.0.2.0
If I use the machine name this works. But is kind of like a hack (because I am just picking the first value of ipv4 address that I get.)
$ipaddress=([System.Net.DNS]::GetHostAddresses('PasteMachineNameHere')|Where-Object {$_.AddressFamily -eq "InterNetwork"} | select-object IPAddressToString)[0].IPAddressToString
Note that you have to replace the value PasteMachineNameHere in the above expression
This works too
$localIpAddress=((ipconfig | findstr [0-9].\.)[0]).Split()[-1]
Here are three methods using windows powershell and/or powershell core, listed from fastest to slowest.
You can assign it to a variable of your choosing.
Method 1: (this method is the fastest and works in both windows powershell and powershell core)
$ipAddress = (Get-NetIPAddress | Where-Object {$_.AddressState -eq "Preferred" -and $_.ValidLifetime -lt "24:00:00"}).IPAddress
Method 2: (this method is as fast as method 1 but it does not work with powershell core)
$ipAddress = (Test-Connection -ComputerName (hostname) -Count 1 | Select -ExpandProperty IPv4Address).IPAddressToString
Method 3: (although the slowest, it works on both windows powershell and powershell core)
$ipAddress = (Get-NetIPConfiguration | Where-Object {$_.IPv4DefaultGateway -ne $null -and $_.NetAdapter.status -ne "Disconnected"}).IPv4Address.IPAddress
Here is what I ended up using
$ipaddress = $(ipconfig | where {$_ -match 'IPv4.+\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' } | out-null; $Matches[1])
which breaks down as
execute ipconfig command - get all the network interface information
use powershell's where filter with a regular expression
regular expression finds the line with "IPv4" and a set of 4 blocks each with 1-3 digits separated by periods, i.e. a v4 IP address
disregard the output by piping it to null
finally get the first matched group as defined by the brackets in the regular expression.
catch that output in $ipaddress for later use.
(Get-WmiObject -Class Win32_NetworkAdapterConfiguration | where {$_.DHCPEnabled -ne $null -and $_.DefaultIPGateway -ne $null}).IPAddress
This one liner gives you the IP address:
(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString
Include it in a Variable?
$IPV4=(Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString
Another variant using $env environment variable to grab hostname:
Test-Connection -ComputerName $env:computername -count 1 | Select-Object IPV4Address
or if you just want the IP address returned without the property header
(Test-Connection -ComputerName $env:computername -count 1).IPV4Address.ipaddressTOstring
tldr;
I used this command to get the ip address of my Ethernet network adapter into a variable called IP.
for /f "tokens=3 delims=: " %i in ('netsh interface ip show config name^="Ethernet" ^| findstr "IP Address"') do set IP=%i
For those who are curious to know what all that means, read on
Most commands using ipconfig for example just print out all your IP addresses and I needed a specific one which in my case was for my Ethernet network adapter.
You can see your list of network adapters by using the netsh interface ipv4 show interfaces command. Most people need Wi-Fi or Ethernet.
You'll see a table like so in the output to the command prompt:
Idx Met MTU State Name
--- ---------- ---------- ------------ ---------------------------
1 75 4294967295 connected Loopback Pseudo-Interface 1
15 25 1500 connected Ethernet
17 5000 1500 connected vEthernet (Default Switch)
32 15 1500 connected vEthernet (DockerNAT)
In the name column you should find the network adapter you want (i.e. Ethernet, Wi-Fi etc.).
As mentioned, I was interested in Ethernet in my case.
To get the IP for that adapter we can use the netsh command:
netsh interface ip show config name="Ethernet"
This gives us this output:
Configuration for interface "Ethernet"
DHCP enabled: Yes
IP Address: 169.252.27.59
Subnet Prefix: 169.252.0.0/16 (mask 255.255.0.0)
InterfaceMetric: 25
DNS servers configured through DHCP: None
Register with which suffix: Primary only
WINS servers configured through DHCP: None
(I faked the actual IP number above for security reasons 😉)
I can further specify which line I want using the findstr command in the ms-dos command prompt.
Here I want the line containing the string IP Address.
netsh interface ip show config name="Ethernet" | findstr "IP Address"
This gives the following output:
IP Address: 169.252.27.59
I can then use the for command that allows me to parse files (or multiline strings in this case) and split out the strings' contents based on a delimiter and the item number that I'm interested in.
Note that I am looking for the third item (tokens=3) and that I am using the space character and : as my delimiters (delims=: ).
for /f "tokens=3 delims=: " %i in ('netsh interface ip show config name^="Ethernet" ^| findstr "IP Address"') do set IP=%i
Each value or token in the loop is printed off as the variable %i but I'm only interested in the third "token" or item (hence tokens=3). Note that I had to escape the | and = using a ^
At the end of the for command you can specify a command to run with the content that is returned. In this case I am using set to assign the value to an environment variable called IP. If you want you could also just echo the value or what ever you like.
With that you get an environment variable with the IP Address of your preferred network adapter assigned to an environment variable. Pretty neat, huh?
If you have any ideas for improving please leave a comment.
I was looking for the same thing and figured this out:
$ip = Get-NetIPAddress -AddressFamily IPv4 -InterfaceIndex $(Get-NetConnectionProfile | Select-Object -ExpandProperty InterfaceIndex) | Select-Object -ExpandProperty IPAddress
This filters out both the loopback address and some virtual networks I have.
$ip = (Get-NetIPAddress -AddressFamily IPv4 -InterfaceIndex $(Get-NetConnectionProfile).InterfaceIndex).IPAddress
OR
function Get-LocalIP {
(
Get-NetIPAddress `
-AddressFamily IPv4 `
-InterfaceIndex $(
Get-NetConnectionProfile
).InterfaceIndex
).IPAddress
}
$ip = Get-LocalIP
To grab the device's IPv4 addresses, and filter to only grab ones that match your scheme (i.e. Ignore and APIPA addresses or the LocalHost address). You could say to grab the address matching 192.168.200.* for example.
$IPv4Addr = Get-NetIPAddress -AddressFamily ipV4 | where {$_.IPAddress -like X.X.X.X} | Select IPAddress

#If you choose, you can merely have the reply by the name and IP, and the Name and no IP by removing the Ping comments
As I was working in Powershell 3, none of the answers here worked for me. It's based on Rob's approach, but this one works when you have multiple network adapters, it also picks out the IP correctly using capture groups
function GetIPConfig {
return ipconfig | select-string ('(\s)+IPv4.+\s(?<IP>(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}))(\s)*') -AllMatches | %{ $_.Matches } | % { $_.Groups["IP"]} | %{ $_.Value }
}
Non of the top comments are actually fully correct since a computer can have multiple interfaces and an interface can have multiple IP addresses. There are a few answers here which technically correct but utilizes "funky" ways to filter out wellknown addresses (like APIPA, localhost, etc) whereas even Powershell 3.0 have a native way to do so with PrefixOrigin.
$IPv4Addresses = $(Get-NetIPAddress | Where-Object { $_.PrefixOrigin -ne "WellKnown" -and $_.AddressFamily -eq "IPv4" }).IPAddress
I do this :
$interFaceAliasName="LAN" # You have to change the name according to your interface's name
$myInterface=(Get-NetIPAddress -InterfaceAlias $interFaceAliasName)
$myIP=$myInterface.IPv4Address
I recently had the same issue. So I wrote a script to parse it from the ipconfig /all output. This script is easily modifiable to obtain any of the parameters of the interfaces and it works on Windows 7 also.
Get output of IP config in LineNumber | Line format
$ip_config = $(ipconfig /all | % {$_ -split "rn"} | Select-String -Pattern ".*" | select LineNumber, Line)
Get list of interfaces (+ last line of ipconfig output) in LineNumber | Line format
$interfaces = $($ip_config | where {$_.Line -notmatch '^\s*$'} | where {$_.Line -notmatch '^\s'}) + $($ip_config | Select -last 1)
Filter through the interfaces list for the specific interface you want
$LAN = $($interfaces | where {$_.Line -match 'Wireless Network Connection:$'})
Get the start and end line numbers of chosen interface from output
$i = $interfaces.IndexOf($LAN)
$start = $LAN.LineNumber
$end = $interfaces[$i+1].LineNumber
Pick the lines from start..end
$LAN = $ip_config | where {$_.LineNumber -in ($start..$end)}
Get IP(v4) address field (returns null if no IPv4 address present)
$LAN_IP = #($LAN | where {$_ -match 'IPv4.+:\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})'})
$LAN_IP = &{If ($LAN_IP.Count -gt 0) {$Matches[1]} Else {$null}}
$a = ipconfig
$result = $a[8] -replace "IPv4 Address. . . . . . . . . . . :",""
Also check which index of ipconfig has the IPv4 Address
I am migrating multiple users from XP to 7 and they all have different mapped drives/locations on their current PC. After copying their all data from old PC to new PC, I am currently manually mapping their drives which consumes lot of time. Is there anyway of automating this process?
Is there any way of running a script on existing XP machine and running the same script on new Win 7 machine to map all the drives?
I am looking for a script or any other way of automating this process.
Thanks.
You could do this for all your users, it would at least tell you what they had.
you'd probably want one central folder, lets say Mappings, so try
net use > \servername\Mappings\%username%_map.txt
Or try something like this
http://www.visualbasicscript.com/List-mapped-drives-on-remote-machine-m28529.aspx
out of boredom i quickly wrote a powershell script to help you out.
Run this on your workstation:
(newpcs and oldpcs must be in correct order so oldpc1 is the old pc of the user of newpc1)
$oldpcs=#("oldpc1", "oldpc2", "oldpc3")
$newpcs = #("newpc1", "newpc2", "newpc3")
$mapping = #{}
for($i=0;$i -lt $oldpcs.Count; $i++){
$mapping.add($oldpcs[$i], $newpcs[$i])
}
foreach ($comp in $oldpcs){
$m = Get-WmiObject win32_systemnetworkconnections -ComputerName $comp
$m | %{
#i know this is not very elegant but whatever
$temp = $_.partcomponent -split "="
$temp = $temp -replace "`"", ""
$temp2= $temp[1] -split " "
$driveletter = $temp2[1] -replace "\(", ""
$driveletter = $driveletter -replace "\)", ""
$path = $temp2[0] -replace "\\\\", "\"
$f = "C:\path\to\folder\" + $mapping.$comp + ".txt"
Add-Content $f "$driveletter;$path"
}
}
Then get the file with corresponding computername to the new computer and run the following:
$txt = Get-Content "C:\path\to\file\$env:computername.txt"
$txt | % {
$temp = $_ -split ";"
net use $temp[0] $temp[1]
}
Remember that you have to run the mapping-script in the context of the user you want to map the drives for
Regards
P.S. Remotely mapping network drives is not possible afaik (i would love to be proven wrong)
You could create a logon script and map it to a user though
