How to get/resolve the command from the alias in PowerShell?

To resolve the command name from given alias, you need to use the below command.

$Alias:AliasName

For example,

$Alias:dir

OR

$Alias:ls

Output

Get-ChildItem

This means the above commands will provide the same result. For example, the output of the below commands would remain the same.

Get-ChildItem C:\
Dir C:\
ls C

Output

You can also use Get-Alias to resolve the alias name. For example,

Get-Alias -Name dir

Get-Alias -Name ls

Until now we need to remember alias name to get the command and we were running individual commands to get the Alias and its command. It is possible to get all the alias names for the given command. To get all aliases for Get-ChildItem.

Get-Alias | where {$_.Definition -eq "Get-ChildItem"}

Output

Get-Alias | where {$_.Definition -eq "Get-Content"}
