定制PowerShell提示 - 相当于CMD的$ M $ P $ _ $ + $ G？

Question

我已经开始与PowerShell“玩耍”，并试图让它“表现”。

一个我想要做的事情是自定义提示是“相似”到什么“$ M $ P $ _ $ + $ G”做MS-DOS：

快速这些做什么的简化：

字符|描述
$ m如果当前驱动器不是网络驱动器，则与当前驱动器号或空字符串关联的远程名称。
$ P电流驱动器和路径
$ _ ENTER-LINEFEED
$ +零个或多个加号（+），这取决于PUSHD目录堆栈的深度字符，一个字符的每个平推
$ G>（大于号）

所以最终的输出是一样的东西：

\\spma1fp1\JARAVJ$ H:\temp 
    ++> 

我已经能够在$M和$_功能（和一个漂亮的历史记录功能）添加到我的提示如下：

function prompt 
{ 
    ## Get the history. Since the history may be either empty, 
    ## a single item or an array, the @() syntax ensures 
    ## that PowerShell treats it as an array 
    $history = @(get-history) 


    ## If there are any items in the history, find out the 
    ## Id of the final one. 
    ## PowerShell defaults the $lastId variable to '0' if this 
    ## code doesn't execute. 
    if($history.Count -gt 0) 
    { 
     $lastItem = $history[$history.Count - 1] 
     $lastId = $lastItem.Id 
    } 

    ## The command that we're currently entering on the prompt 
    ## will be next in the history. Because of that, we'll 
    ## take the last history Id and add one to it. 
    $nextCommand = $lastId + 1 

    ## Get the current location 
    $currentDirectory = get-location 

    ## Set the Windows Title to the current location 
    $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory 

    ## And create a prompt that shows the command number, 
    ## and current location 
    "PS:$nextCommand $currentDirectory 
>" 
} 

但剩下的就是没有的东西我已经成功地复制...

非常感谢您的提示，一定会来！

看看这个你想要做什么：

function prompt 
{ 
    ## Get the history. Since the history may be either empty, 
    ## a single item or an array, the @() syntax ensures 
    ## that PowerShell treats it as an array 
    $history = @(get-history) 


    ## If there are any items in the history, find out the 
    ## Id of the final one. 
    ## PowerShell defaults the $lastId variable to '0' if this 
    ## code doesn't execute. 
    if($history.Count -gt 0) 
    { 
     $lastItem = $history[$history.Count - 1] 
     $lastId = $lastItem.Id 
    } 

    ## The command that we're currently entering on the prompt 
    ## will be next in the history. Because of that, we'll 
    ## take the last history Id and add one to it. 
    $nextCommand = $lastId + 1 

    ## Get the current location 
    $currentDirectory = get-location 

    ## Set the Windows Title to the current location 
    $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory 

    ##pushd info 
    $pushdCount = $(get-location -stack).count 
    $pushPrompt = "" 
    for ($i=0; $i -lt $pushdCount; $i++) 
    { 
     $pushPrompt += "+" 
    } 

    ## And create a prompt that shows the command number, 
    ## and current location 
    "PS:$nextCommand $currentDirectory `n$($pushPrompt)>" 
} 

Answer 2

这将让你在PUSHD栈上的位置的计数：

$(get-location -Stack).count 

Answer 3

由于EBGReens的回答，我的“提示”是现在能够显示堆栈的深度：

function prompt 
{ 
    ## Initialize vars 
    $depth_string = "" 

    ## Get the Stack -Pushd count 
    $depth = (get-location -Stack).count 

    ## Create a string that has $depth plus signs 
    $depth_string = "+" * $depth 

    ## Get the history. Since the history may be either empty, 
    ## a single item or an array, the @() syntax ensures 
    ## that PowerShell treats it as an array 
    $history = @(get-history) 


    ## If there are any items in the history, find out the 
    ## Id of the final one. 
    ## PowerShell defaults the $lastId variable to '0' if this 
    ## code doesn't execute. 
    if($history.Count -gt 0) 
    { 
     $lastItem = $history[$history.Count - 1] 
     $lastId = $lastItem.Id 
    } 

    ## The command that we're currently entering on the prompt 
    ## will be next in the history. Because of that, we'll 
    ## take the last history Id and add one to it. 
    $nextCommand = $lastId + 1 

    ## Get the current location 
    $currentDirectory = get-location 

    ## Set the Windows Title to the current location 
    $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory 

    ## And create a prompt that shows the command number, 
    ## and current location 
    "PS:$nextCommand $currentDirectory `n$($depth_string)>" 
} 

Answer 4

以下将给你相当于$ m。

$mydrive = $pwd.Drive.Name + ":"; 
$networkShare = (gwmi -class "Win32_MappedLogicalDisk" -filter "DeviceID = '$mydrive'"); 

if ($networkShare -ne $null) 
{ 
    $networkPath = $networkShare.ProviderName 
} 

Answer 5

多亏提示：

In PowerShell, how can I determine if the current drive is a networked drive or not?
In PowerShell, how can I determine the root of a drive (supposing it's a networked drive)

我已经成功地得到它的工作。

我的完整个人资料是：

function prompt 
{ 
    ## Initialize vars 
    $depth_string = "" 

    ## Get the Stack -Pushd count 
    $depth = (get-location -Stack).count 

    ## Create a string that has $depth plus signs 
    $depth_string = "+" * $depth 

    ## Get the history. Since the history may be either empty, 
    ## a single item or an array, the @() syntax ensures 
    ## that PowerShell treats it as an array 
    $history = @(get-history) 


    ## If there are any items in the history, find out the 
    ## Id of the final one. 
    ## PowerShell defaults the $lastId variable to '0' if this 
    ## code doesn't execute. 
    if($history.Count -gt 0) 
    { 
     $lastItem = $history[$history.Count - 1] 
     $lastId = $lastItem.Id 
    } 

    ## The command that we're currently entering on the prompt 
    ## will be next in the history. Because of that, we'll 
    ## take the last history Id and add one to it. 
    $nextCommand = $lastId + 1 

    ## Get the current location 
    $currentDirectory = get-location 

    ## Set the Windows Title to the current location 
    $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory 

     ## Get the current location's DRIVE LETTER 
     $drive = (get-item ($currentDirectory)).root.name 

     ## Make sure we're using a path that is not already UNC 
     if ($drive.IndexOf(":") -ne "-1") 
      { 
       $root_dir = (get-wmiobject Win32_LogicalDisk | ? {$_.deviceid -eq $drive.Trim("\") } | % { $_.providername })+" " 
      } 
      else 
      { 
      $root_dir="" 
      } 


    ## And create a prompt that shows the command number, 
    ## and current location 
    "PS:$nextCommand $root_dir$currentDirectory `n$($depth_string)>" 
}
