如何在Powershell会话期间重新定义提示功能

Question

在shell启动后，是否可以重新定义用户配置文件中指定的提示函数？

Answer 1

要随时更改提示函数，只需在PowerShell命令行中执行如下语句：

function prompt { "$env:computername $pwd>" }

Answer 2

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 " "
}
