自定义PowerShell提示符-相当于CMD的$M$P$_$+$G?

我已经开始“玩弄”PowerShell,并试图让它“正常运转”。
我想做的一件事是将提示自定义为“类似于”MS-Dos 上的“$M$P$_$+$G”:
快速概述一下它们的作用:
特点|描述
百万美元 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
$_ 回车换行
$+ 零个或多个加号 (+) 字符,具体取决于深度 推送 目录堆栈,每一层压入一个字符
$克 >(大于号)
所以最终的输出是这样的:
\\spma1fp1\JARAVJ$ H:\temp
++>
我已经能够添加 $M
和 $_
我的提示的功能(和一个漂亮的历史记录功能)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
>"
}
但其余的还不是我能够复制的......
非常感谢您一定会提供的提示!
解决方案
看看这是否符合您的要求:
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)>"
}
其他提示
这将为您提供 Pushd 堆栈上位置的计数:
$(get-location -Stack).count
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)>"
}
以下将为您提供相当于 $m 的金额。
$mydrive = $pwd.Drive.Name + ":";
$networkShare = (gwmi -class "Win32_MappedLogicalDisk" -filter "DeviceID = '$mydrive'");
if ($networkShare -ne $null)
{
$networkPath = $networkShare.ProviderName
}

在PowerShell中,如何确定驱动器的根(假设它是网络驱动器)
我已经成功让它发挥作用了。
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)>"
}
