What is a PowerShell Alias
A PowerShell alias is another name assigned to a cmdlet. PowerShell cmdlet names follow a Verb-Noun convention which can be cumbersome to type and use. To minimize typing, and to make it easier for users accustomed to other shells like Windows Command Prompt or Unix shells, Windows PowerShell supports the concept of an alias. Simply, alias is an alternate name for a cmdlet.
