Is it possible to redefine the prompt function specified in the user's profile after the shell has started?

To customize the prompt, write a new Prompt function. The function is not protected, so you can overwrite it. Then, between the braces, enter the commands or the string that creates your prompt. The following Prompt function displays the history ID of the next command.
Press Ctrl + Shift + 2 while the Terminal window is in focus. This opens a new tab with the Command Prompt shell. You can now close the first tab and start working using CMD. To close the first tab, click on the X button next to the Windows PowerShell tab name.
You can interrupt and stop a PowerShell command while it is running by pressing Control-C. A script can be stopped with the command exit. This will also close the PowerShell console.
PowerShell uses the parameter value order to associate each parameter value with a parameter in the function. When you use positional parameters, type one or more values after the function name. Positional parameter values are assigned to the $args array variable.
To change the prompt function at any time, just execute a statement like the following at the PowerShell command line:
function prompt { "$env:computername $pwd>" }
Yes, just enter code as normal:
function prompt
{
$random = new-object random
$color=[System.ConsoleColor]$random.next(1,16)
Write-Host ("PS " + $(get-location) +">") -nonewline -foregroundcolor $color
return " "
}
