This cmdlet allows you to create new alternate names for exiting cmdlets

PS C:\> Set-Alias -Name proc -Value Get-Process
PS C:\> proc

Keep in mind that any alias you create will be persisted only in current session. When you start new session you need to create your aliases again. Powershell Profiles (see [topic not yet created]) are great for these purposes.
