How to create large dummy files

2013.03.27 | Bez komentářů

For example, to create ten dummy files c:\temp\file* with the size of 1GiB :

0..9 | foreach {fsutil file createnew "c:\temp\file$_" 1073741824}

1	0..9 \| foreach {fsutil file createnew "c:\temp\file$_" 1073741824}

This script will check a disk’s free space and send a warning if the server has dropped below the limit you have specified.
The settings are in a XML file. The main entity is the filesystem – let’s say a drive letter or disk. Each disk must be defined as an element, which includes values such as the hostname, limit, and list of recipents.
Both files for this solution must be in the same folder.

$ScriptPath = $MyInvocation.MyCommand.Path

$Timestamp = Get-Date -Format "yyyy.MM.dd HH:mm"

foreach ($Item in $Settings.freeSpaceWatchdog.filesystem) {

    $ComputerName = $($Item.Hostname)
    $Disk = $($Item.Volume)
    $Limit = [math]::round($($Item.Limit), 2)
    $EmailRecipients = $($Item.EmailRecipients)

    $Data = Get-WmiObject Win32_LogicalDisk -ComputerName $ComputerName -Filter "DeviceID='$Disk'" |
        Select-Object FreeSpace, Size

    $Size = [math]::round($Data.Size / 1GB, 2)
    $FreeSpace = [math]::round($Data.FreeSpace / 1GB, 2)

    if ($FreeSpace -le $Limit) {
        "$Timestamp - Warning - $Comptername disk $Disk, limit $Limit, freespace $Freespace" >> $Log

Optimize PowerShell Performance

2013.03.07 | Bez komentářů

I often need to retrieve data from Active Directory in many iterations which is very demanding and consumes all the RAM. Processing gradually slows down as well. Off course, a reduced amount of data could help (http://dmitrysotnikov.wordpress.com/2007/07/24/optimize-powershell-performance-and-memory-consumption/). But sometimes it could be better to use a multi-dimensional hash table to temporarily store data from AD rather than reading the data in each iteration. Reading data from a local variable is more effective.

How to add a few attributes to our hash table called ‘ADUsersCache’ in example below:

$SearchRoot = "OU=Users,DC=Domain,DC=Local"
$SizeLimit = "0"
$ADUsersCache=@{}

if ( (Get-PSSnapin -Name quest.activeroles.admanagement -ErrorAction SilentlyContinue) -eq $Null ){
    Add-PsSnapin quest.activeroles.admanagement
}

$ADUsers = Get-QADUser -SearchRoot $SearchRoot -SizeLimit $SizeLimit -DontUseDefaultIncludedProperties `
    -IncludedProperties Name, LogonName, LogonScript, PrimarySMTPAddress, Title, Department

foreach ($ADUser in $ADUsers) {

    $Name = $ADuser.Name
    $LogonName = $ADuser.LogonName
    $LogonScript = $ADuser.LogonScript
    $PrimarySMTPAddress = $ADuser.PrimarySMTPAddress    
    $Title = $ADuser.Title

    $ADUsersCache += @{
        "$LogonName" = @{
            "Name"="$Name";
            "LogonScript"="$LogonScript";
            "PrimarySMTPAddress"="$PrimarySmtpAddress";
            "Title"="$Title"
            "Department"="$Department"
        } 
    }

}

$SearchRoot = "OU=Users,DC=Domain,DC=Local"

$SizeLimit = "0"

$ADUsersCache=@{}

if ( (Get-PSSnapin -Name quest.activeroles.admanagement -ErrorAction SilentlyContinue) -eq $Null ){

Add-PsSnapin quest.activeroles.admanagement

}

$ADUsers = Get-QADUser -SearchRoot $SearchRoot -SizeLimit $SizeLimit -DontUseDefaultIncludedProperties `

-IncludedProperties Name, LogonName, LogonScript, PrimarySMTPAddress, Title, Department

foreach ($ADUser in $ADUsers) {

$Name = $ADuser.Name

$LogonName = $ADuser.LogonName

$LogonScript = $ADuser.LogonScript

$PrimarySMTPAddress = $ADuser.PrimarySMTPAddress

$Title = $ADuser.Title

$ADUsersCache += @{

"$LogonName" = @{

"Name"="$Name";

"LogonScript"="$LogonScript";

"PrimarySMTPAddress"="$PrimarySmtpAddress";

"Title"="$Title"

"Department"="$Department"

}

Than i can work with…

$MyProperty = $ADUsersCache.GetEnumerator() | Where-Object {$_.Value.Title -ilike "*sales*"}
$MyProperty.Key

1 2	$MyProperty = $ADUsersCache.GetEnumerator() \| Where-Object {$_.Value.Title -ilike "sales"} $MyProperty.Key

Changing the prompt in a win cmd

2012.12.12 | Bez komentářů

The default Linux prompt gives you additional helpful information while working through a session instead of Windows.
The example below displays a user who is logged in along with the hostname in a windows command line.

C:\Windows\system32>set prompt=[%username%@%computername% $P]#

[strachotao@PC101 C:\Windows\system32]#

C:\Windows\system32>set prompt=[%username%@%computername% $P]#

[strachotao@PC101 C:\Windows\system32]#
