The command "Get-Alias" retrieves all the defined aliases in PowerShell. An alias is a shorthand or alternate name for a cmdlet or command. For example, "ls" is an alias for the "Get-ChildItem" cmdlet.
The "|" symbol is the pipeline operator, which directs the output of the preceding command (Get-Alias) as input to the next command.
The "Out-String" cmdlet converts the output into a string format. By default, it concatenates the output objects into a single, multiline string.
The "-Stream" parameter used with "Out-String" ensures that each input object is converted to a separate string. This means that each alias will be outputted individually as a string.
So, the full command "Get-Alias | Out-String -Stream" lists all the aliases defined in PowerShell, with each alias displayed as a separate string.
