This repo contains some PS scripts that i often use. This readme contains the explanation of how to use.

Currently, this repo contains the following scripts:

• Add alias for Office 365 email
• Get IP addresses by host name(s)
• Multiple Git operations
• Unzip all files directly into the current working directory

Powershell's PATH environment variable works a little different than the old command line. To add the scripts to the PATH environment, add the path to the registry:

• HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment
• Key: Path

Add a mail alias for an Office 365 mail account using a simple Powershell script

Install he ExchangeOnlineManagement Powershell module using the command:

Install-Module ExchangeOnlineManagement

Set the following settings in the script:

$mailbox = "[email protected]"
$aliasDomain = "@domain.com"
$adminPrincipal = "[email protected]"

mailbox The mailbox is where to create the alias for.

aliasDomain The domain that the alias will be created for. This will be the domain that is used for the $mailbox.

adminPrincipal The email address of the administrator account that you will use to create the alias. This can of course be the same as the $mailbox, but it can also be a different one.

Get IP addresses for hostnames.

Call this script with the domain name(s) you want to get the IP address of. Example: .\Get-Ips-By-Host.ps1 google.com microsoft.com azure.com

This will give you the following output:

IP                  | Hostname
--------------------+------------------------------
142.250.179.174     | google.com
40.113.200.201      | microsoft.com
13.94.192.98        | azure.com

Executes git checkout in all subdirectories of the current working dir.

Call this script from within a directory that contains (multiple) git repos, each in their own (sub)directory. .\Git-Checkout.ps1

You can also specify the branch you want to checkout directly by running: .\Git-Checkout.ps1 branchname

The branch must exist locally, it does not create it from a remote branch when not checked out earlier.

Executes git fetch in all subdirectories of the current working dir.

Call this script from within a directory that contains (multiple) git repos, each in their own (sub)directory. .\Git-Fetch.ps1

Executes git pull in all subdirectories of the current working dir.

Call this script from within a directory that contains (multiple) git repos, each in their own (sub)directory. .\Git-Pull.ps1

Extract all the zip files in a directory, straight into the directory. So if there is no folder structure inside the zip file, all the files will go directly to the working directory.
