您的个人资料中有哪些基本内容（功能，别名，启动脚本）？
Answers:
我经常发现自己需要一些基本的合计来计算/求和一些东西。我定义了这些函数并经常使用它们，它们在管道的末尾运行得非常好：
#
# useful agregate
#
function count
{
BEGIN { $x = 0 }
PROCESS { $x += 1 }
END { $x }
}
function product
{
BEGIN { $x = 1 }
PROCESS { $x *= $_ }
END { $x }
}
function sum
{
BEGIN { $x = 0 }
PROCESS { $x += $_ }
END { $x }
}
function average
{
BEGIN { $max = 0; $curr = 0 }
PROCESS { $max += $_; $curr += 1 }
END { $max / $curr }
}
为了能够在提示下获得带有颜色的时间和路径：
function Get-Time { return $(get-date | foreach { $_.ToLongTimeString() } ) }
function prompt
{
# Write the time
write-host "[" -noNewLine
write-host $(Get-Time) -foreground yellow -noNewLine
write-host "] " -noNewLine
# Write the path
write-host $($(Get-Location).Path.replace($home,"~").replace("\","/")) -foreground green -noNewLine
write-host $(if ($nestedpromptlevel -ge 1) { '>>' }) -noNewLine
return "> "
}
以下功能是从博客中窃取的，并根据我的口味进行了修改，但是带有颜色的ls非常好：
# LS.MSH
# Colorized LS function replacement
# /\/\o\/\/ 2006
# http://mow001.blogspot.com
function LL
{
param ($dir = ".", $all = $false)
$origFg = $host.ui.rawui.foregroundColor
if ( $all ) { $toList = ls -force $dir }
else { $toList = ls $dir }
foreach ($Item in $toList)
{
Switch ($Item.Extension)
{
".Exe" {$host.ui.rawui.foregroundColor = "Yellow"}
".cmd" {$host.ui.rawui.foregroundColor = "Red"}
".msh" {$host.ui.rawui.foregroundColor = "Red"}
".vbs" {$host.ui.rawui.foregroundColor = "Red"}
Default {$host.ui.rawui.foregroundColor = $origFg}
}
if ($item.Mode.StartsWith("d")) {$host.ui.rawui.foregroundColor = "Green"}
$item
}
$host.ui.rawui.foregroundColor = $origFg
}
function lla
{
param ( $dir=".")
ll $dir $true
}
function la { ls -force }
还有一些避免真正重复过滤任务的捷径：
# behave like a grep command
# but work on objects, used
# to be still be allowed to use grep
filter match( $reg )
{
if ($_.tostring() -match $reg)
{ $_ }
}
# behave like a grep -v command
# but work on objects
filter exclude( $reg )
{
if (-not ($_.tostring() -match $reg))
{ $_ }
}
# behave like match but use only -like
filter like( $glob )
{
if ($_.toString() -like $glob)
{ $_ }
}
filter unlike( $glob )
{
if (-not ($_.tostring() -like $glob))
{ $_ }
}
要从PowerShell设置我的Visual Studio构建环境，我从这里安装了VsVars32 。并一直使用它。
############################################### ############################
＃批量公开环境变量，并在此PS会话中进行设置
############################################### ############################
函数Get-Batchfile（$ file）
{
$ theCmd =“`” $ file`“＆set”
cmd / c $ theCmd | Foreach对象{
$ thePath，$ theValue = $ _。split（'='）
Set-Item -path env：$ thePath -value $ theValue
}
}
############################################### ############################
＃设置此PS会话要使用的VS变量
############################################### ############################
函数VsVars32（$ version =“ 9.0”）
{
$ theKey =“ HKLM：SOFTWARE \ Microsoft \ VisualStudio \” + $ version
$ theVsKey = get-ItemProperty $ theKey
$ theVsInstallPath = [System.IO.Path] :: GetDirectoryName（$ theVsKey.InstallDir）
$ theVsToolsDir = [System.IO.Path] :: GetDirectoryName（$ theVsInstallPath）
$ theVsToolsDir = [System.IO.Path] :: Combine（$ theVsToolsDir，“工具”）
$ theBatchFile = [System.IO.Path] :: Combine（$ theVsToolsDir，“ vsvars32.bat”）
获取批处理文件$ theBatchFile
[System.Console] :: Title =“ Visual Studio” + $ version +“ Windows Powershell”
}
这将通过脚本PSDrive进行迭代，并以点源方式源以“ lib-”开头的所有内容。
### ---------------------------------------------------------------------------
### Load function / filter definition library
### ---------------------------------------------------------------------------
Get-ChildItem scripts:\lib-*.ps1 | % {
. $_
write-host "Loading library file:`t$($_.name)"
}
开始成绩单。这会将整个会话写到一个文本文件中。非常适合培训新员工如何在环境中使用Powershell。
我的提示包含：
$width = ($Host.UI.RawUI.WindowSize.Width - 2 - $(Get-Location).ToString().Length)
$hr = New-Object System.String @('-',$width)
Write-Host -ForegroundColor Red $(Get-Location) $hr
这使我可以在滚动命令时轻松看到命令之间的分隔线。它还向我显示了当前目录，但没有在我键入的行上使用水平空格。

死书呆子：

# Need to still show the working directory.
#Write-Host "You landed in $PWD"
# Nerd up, yo.

我可以使用PowerShell进行的所有必需操作都在这里...
# Explorer command

)]
[ValidateNotNullOrEmpty()]
[string]
# First parameter is the path you're going to explore.
$Target
)
$exploration = New-Object -ComObject shell.application
$exploration.Explore($Target)
}
我仍然是管理员，所以我需要...
Function RDP
{
param
(
[Parameter(
Position = 0,
ValueFromPipeline = $true,
Mandatory = $true,
HelpMessage = "Server Friendly name"
)]
[ValidateNotNullOrEmpty()]

)
cmdkey /generic:TERMSRV/$server /user:$UserName /pass:($Password.GetNetworkCredential().Password)
mstsc /v:$Server /f /admin
Wait-Event -Timeout 5
cmdkey /Delete:TERMSRV/$server
}
有时我想以登录用户以外的其他人身份启动资源管理器...
# Restarts explorer as the user in $UserName
function New-Explorer
{
# CLI prompt for password
taskkill /f /IM Explorer.exe
runas /noprofile /netonly /user:$UserName explorer
}
这只是因为它很有趣。

我也有一个，因为Win+L距离太远了...

public static extern bool LockWorkStation();
"@
$LockWorkStation = Add-Type -memberDefinition $signature -name "Win32LockWorkStation" -namespace Win32Functions -passthru

filter FileSizeAbove($size){if($_.Length -ge $size){$_}}
我还有一些我无法发布，因为它们还没有完成，但是它们基本上是在会话之间保留凭据的一种方式，而无需将其写为加密文件。
# ----------------------------------------------------------
# msdn search for win32 APIs.
# ----------------------------------------------------------

$url += $args[$i];
}
$url += '&locale=en-us&refinement=86&ac=3';

# ----------------------------------------------------------

# ----------------------------------------------------------
function Open-IE ($url)
{
$ie = new-object -comobject internetexplorer.application;
$ie.Navigate($url);
$ie.Visible = $true;
}
Open-IE使用的内置ii别名Invoke-Item。
start http://google.com
我添加了此功能，以便可以轻松查看磁盘使用情况：
function df {
$colItems = Get-wmiObject -class "Win32_LogicalDisk" -namespace "root\CIMV2" `
-computername localhost
foreach ($objItem in $colItems) {
write $objItem.DeviceID $objItem.Description $objItem.FileSystem `
($objItem.Size / 1GB).ToString("f3") ($objItem.FreeSpace / 1GB).ToString("f3")
}
}
适当的。
尽管我认为这已被最近或即将发布的版本所取代。

对于使用xml很有用，例如带--xml的svn命令的输出。
这会将您已安装的管理单元添加到powershell会话中。您可能想要执行类似操作的原因是，它易于维护，并且如果您在多个系统上同步配置文件，则效果很好。如果未安装管理单元，则不会看到错误消息。
$snapins = @(
"Quest.ActiveRoles.ADManagement",
"PowerGadgets",
"VMware.VimAutomation.Core",
"NetCmdlets"

Add-PSSnapin $_
}
}
我将所有函数和别名放在单独的脚本文件中，然后在配置文件中点按它们的源代码：
。c：\ scripts \ posh \ jdh-functions.ps1
您可以在http://github.com/jamesottaway/windowspowershell上查看我的PowerShell配置文件
如果您使用Git将我的存储库克隆到Documents文件夹（或$ PROFILE变量中“ WindowsPowerShell”上方的任何文件夹）中，您将大受好评。
主体profile.ps1将子文件夹的名称设置Addons为PSDrive，然后在该文件夹下找到所有要加载的.ps1文件。
我非常喜欢该go命令，该命令存储了一个简明位置字典，可以轻松访问。例如，go vsp带我去C:\Visual Studio 2008\Projects。

我将个人资料保留为空。相反，我有一些脚本文件夹，可以浏览以将功能和别名加载到会话中。文件夹将是模块化的，带有功能和程序集库。对于临时工作，我将有一个脚本来加载别名和函数。如果要清除事件日志，请导航到脚本\ eventlogs文件夹并执行
PS > . .\DotSourceThisToLoadSomeHandyEventLogMonitoringFunctions.ps1
之所以这样做，是因为我需要与他人共享脚本或将脚本从一台计算机移到另一台计算机。我希望能够复制脚本和程序集的文件夹，并使它可以在任何用户的任何计算机上运行。
但是您想要有趣的花样收藏。这是我的许多“配置文件”所依赖的脚本。它允许调用使用自签名SSL的Web服务，以对开发中的Web服务进行临时探索。是的，我在Powershell脚本中随意混合使用C＃。
# Using a target web service that requires SSL, but server is self-signed.
# Without this, we'll fail unable to establish trust relationship.

好问题。因为我要处理几个不同的PowerShell主机，所以我要在几个配置文件中分别进行一点登录，只是为了使其他任何消息的上下文更清晰。在中profile.ps1，我目前只有该功能，但有时会根据上下文进行更改：
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
我最喜欢的主机是ISE，在中Microsoft.PowerShellIse_profile.ps1，我有：
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
if ( New-PSDrive -ErrorAction Ignore One FileSystem `
(Get-ItemProperty hkcu:\Software\Microsoft\SkyDrive UserFolder).UserFolder) {
Write-Host -ForegroundColor Green "PSDrive One: mapped to local OneDrive/SkyDrive folder"
}
Import-Module PSCX
$PSCX:TextEditor = (get-command Powershell_ISE).Path
$PSDefaultParameterValues = @{
"Get-Help:ShowWindow" = $true
"Help:ShowWindow" = $true
"Out-Default:OutVariable" = "0"
}
