PowerShell is an extensible command-line shell and associated scripting language developed by Microsoft that can be used to help automate common administration tasks and also provide information about your VMware environment. PowerShell can be used for many different things in Windows environments but can also be used with VMware environments since VMware released their VI Toolkit which provides PowerShell with access to the VMware API. Scripting is a great way to make up for a product's shortcomings or missing features and can be a real time saver for administrators. Consequently many systems administrators learn a bit of scripting and write their own scripts to make their job easier. PowerShell is fairly easy to install and use and there are many great scripts that have been written that work with VMware environments. This list consists of some great scripts that have been written by many different individuals that help automate and report on VMware environments.
