【中文标题】自定义 PowerShell 提示 - 相当于 CMD 的 $M$P$_$+$G?【英文标题】：Customizing PowerShell Prompt - Equivalent to CMD's $M$P$_$+$G? 【发布时间】：2010-09-14 13:10:15 【问题描述】：我已经开始“玩弄” PowerShell，并试图让它“表现”。
我想做的一件事是将 PROMPT 自定义为“类似于”在 MS-Dos 上执行的“$M$P$_$+$G”：
这些功能的简要说明：
人物|说明$m 与当前驱动器号关联的远程名称，如果当前驱动器不是网络驱动器，则为空字符串。 $p 当前驱动器和路径 $_ ENTER-LINEFEED $+ 零个或多个加号（+ ) 字符取决于 pushd 目录堆栈的深度，每个推送的级别一个字符 $g >（大于号）
所以最终的输出是这样的：
\\spma1fp1\JARAVJ$ H:\temp
++>
我已经能够将$M 和$_ 功能（和一个漂亮的历史功能）添加到我的提示中，如下所示：
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
>"
但其余的还不是我设法复制的东西......
非常感谢您肯定会提供的提示！

【参考方案1】：感谢以下提示：
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)
我已经设法让它工作了。
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)>"

【参考方案2】：以下将为您提供 $m 的等价物。
$mydrive = $pwd.Drive.Name + ":";
$networkShare = (gwmi -class "Win32_MappedLogicalDisk" -filter "DeviceID = '$mydrive'");
if ($networkShare -ne $null)
$networkPath = $networkShare.ProviderName

【参考方案3】：感谢 EBGReens 的回答，我的“提示”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)>"

忘了乘以字符串。那里很好抓。今天早上太多vbscript。 :(。【参考方案4】：看看这是不是你想要的：
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)>"
【讨论】：
【参考方案5】：这将为您提供 pushd 堆栈上的位置计数：
$(get-location -Stack).count
