## Custom pre-prompt and pre-execution Commands in PowerShell
|
||||
|
||||
PowerShell does not have a formal preexec/precmd framework like most other shells.
|
||||
Because of this, it is difficult to provide fully customizable hooks in `powershell`.
|
||||
However, Starship does give you limited ability to insert your own functions
|
||||
into the prompt-rendering procedure:
|
||||
|
||||
Create a function named `Invoke-Starship-PreCommand`
|
||||
|
||||
```powershell
|
||||
function Invoke-Starship-PreCommand {
|
||||
$host.ui.Write("🚀")
|
||||
}
|
||||
```
|

You can also set a similar output with PowerShell by creating a function named `Invoke-Starship-PreCommand`.

```powershell

# edit $PROFILE
|

function Invoke-Starship-PreCommand {

## Enable Right Prompt

Some shells support a right prompt which renders on the same line as the input. Starship can
