我开始“玩”使用PowerShell，我试图得到它的“表现”。
有一个问题我想做的事情是自定义提示是“相似”到什么“$ M $ P $ _ $ + $ G”做MS-DOS：
什么这些做一简要介绍：
汉字 | 描述
$ M与当前的驱动器号或空字符串有关联的远程名称，如果当前驱动器不是网络驱动器。
$ P当前驱动器和路径
$ _回车换行符
$ +零个或多个加号（+），这取决于PUSHD目录堆栈的深度的字符，对每个级别的一个字符推
$克 >（大于号）
所以最终的输出是一样的东西：
\\spma1fp1\JARAVJ$ H:\temp
++>
我已经能够添加$M和$_功能（和一个漂亮的历史记录功能），以我的提示如下：
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
>"
}
但其余的还没有的东西我已经成功地复制....
非常感谢，一定会来的提示！
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)>"
}
这将让你在PUSHD栈上的位置的计数：
$(get-location -Stack).count
由于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 $currentDirectory `n$($depth_string)>"
}
下面将为你的$ M相当。
$mydrive = $pwd.Drive.Name + ":";
$networkShare = (gwmi -class "Win32_MappedLogicalDisk" -filter "DeviceID = '$mydrive'");
if ($networkShare -ne $null)
{
$networkPath = $networkShare.ProviderName
}
由于在小窍门：
在PowerShell中，我怎么能确定当前的驱动器是一个网络驱动器或不？
在PowerShell中，我怎么能确定一个驱动器的根（假设它是一个网络驱动器）
我已经成功地得到它的工作。
我的完整的个人资料如下：
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)>"
}
