PowerShell Script: Zip up a folder and email it

Published by ryangl March 4th, 2008 in Powershell and Scripts. 0 Comments

Cool method for scripting attaching a file and emailing using Powershell.  The script also displays how to zip up a destination using Out-zip.

$sender = sender@host.com
$recipient = recipient@host.com
$server = mail.host.com
$targetFolder = c:\MyFolder
$file = c:\MyZipFile.zip if ( [System.IO.File]::Exists($file) )
{
  remove-item -force $file
}

gi $targetFolder | out-zip $file $_
$subject = “Sending a File ” + [System.DateTime]::Now
$body = “I’m sending a file!”
$msg = new-object System.Net.Mail.MailMessage $sender, $recipient, $subject, $body
$attachment = new-object System.Net.Mail.Attachment $file
$msg.Attachments.Add($attachment)
$client = new-object System.Net.Mail.SmtpClient $server
$client.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
$client.Send($msg)

Windows PowerShell : Show-WmiClass

Published by ryangl September 2nd, 2007 in Downloads, Powershell, Scripts and WMI. 0 Comments

Jeffrey Snover of Microsoft posted this script to provide a simple way to show WMI Classes within PowerShell.

Here is a script that I use to show WMI classes. I think you’ll find it useful. There is an example after the script:

##############################
# Show-WmiClass - Show WMI classes
# Author: Microsoft
# Version: 1.0
# NOTE: Notice that this is uses the verb SHOW vs GET. That is because it
# combines a Getter with a format. SHOW was added as a new “official
# verb to deal with just this case.
#############################
param(
$Name = “.”,
$NameSpace = “root\cimv2″,
[Switch]$Refresh=$false
)
# Getting a list of classes can be expensive and the list changes infrequently.
# This makes it a good candidate for caching.
$CacheDir = Join-path $env:Temp “WMIClasses”
$CacheFile = Join-Path $CacheDir ($Namespace.Replace(”\”,”-”) + “.csv”)
if (!(Test-Path $CacheDir))
{
$null = New-Item -Type Directory -Force $CacheDir
}
if (!(Test-Path $CacheFile) -Or $Refresh)
{
Get-WmiObject -List -Namespace:$Namespace |
Sort -Property Name |
Select -Property Name |
Export-csv -Path $CacheFile -Force
}
Import-csv -Path $CacheFile |
where {$_.Name -match $Name} |
Format-Wide -AutoSize
###### EOF ###########

Allowing scripts to be run via PowerShell

Published by ryangl August 16th, 2007 in Active Directory, Downloads, Management, Powershell and Tools. 0 Comments

Running scripts via Powershell is disable by default.  There is a key to note that you can run commands or cmdlets from the PowerShell console, just not scripts.  To enable this feature you can do one of two things, however one trumps the other:

Via PowerShell

Modify your ExecutionPolicy via the Set-Execution cmdlet

First run Get-ExecutionPolicy to see what level you are at.  By default, this setting is set to Restricted. 

To see what settings are available for you to set, you can type

Get-Help Set-ExecutionPolicy

This output shows that we have four options:  Restricted, AllSigned, RemoteSigned, and Unrestricted.

To set your ExecutionPolicy to Unrestricted (not recommended for production) you would enter:

Set-ExecutionPolicy Unrestricted

To validate you settings after running the Set-ExecutionPolicy, run:

Get-ExecutionPolicy

From the command above, your ExecutionPolicy is now set to Unrestricted.  You can now run any scripts you like, signed or unsigned. (Bet your administrator is happy to hear that!)

Now for the other method for setting this policy

Via Group Policy

Seeing how the first method would be a nightmare to manage, Microsoft has released the ADM files for PowerShell that allow you to configure this setting via Group Policy.  Any settings made via Group Policy will overwrite those set manually via the PowerShell Console. 

powershellADM

Active Directory Account Management using PowerShell

Published by ryangl August 14th, 2007 in Active Directory, Management, Powershell, Windows Server 2003 and Windows Server 2008. 0 Comments

 PowerShell and the Quest Active Directory cmdlets are a dream come true for any AD Administrator.  Methods that used to take more complicated means are now simple one-liners.  

One of the nice improvements of AD cmdlets 1.0.4 is the way you can get enable, disable, and unlock AD user accounts with simple one-liners.

Here are a few oneliners demonstrating the new functionality:

#Get all disabled accounts
Get-QADUser -Disabled $true

#Get all locked accounts in the accounting department
Get-QADUser -Locked $true -Department Accounting

#Enable all the disabled accounts
Get-QADUser -Disabled $true | Enable-QADUser

#Unlock a specific user account
Unlock-QADUser DSotnikov

The little things

Published by ryangl August 4th, 2007 in Powershell and Tools. 0 Comments

I once had a coach in high school that would always, and I mean always stress the little things.  “Its the little things that make the big things”; we would hear that daily.  After playing around with Powershell at home, I started laughing because I heard that voice say that phrase as I used a single line to organize all of my scattered .iso files on my 1TB external drive. 

I always wanted to re-organize the files on this drive, but using any search feature took a long time, and time is not something I have much of.  So again, the little things.

From the PowerShell console, I was wondering in what locations were all of my ISO files?  I entered:

Get-ChildItem -path E:\ -Recurse -Include *.iso > ISO.txt

This command searched for every ISO on the external drive (E:) and piped it out to a text file.  Viewing that text file, I found out what I thought…I had ISO files everywhere.  No big deal, I’ll just modify the command above to move everything to a central repository.

Get-ChildItem -path E:\ -Recurse -Include *.iso | move-item -Destination e:\ISO\

Easy peasy, command completed and now i’m going to re-run my audit of where my ISO files are and we see that they are now all located in the -Destination directory.

Clean-up made simple!
