我经常发现自己需要一些基本的聚合来计算/求和一些东西。我已经定义了这些函数并经常使用它们，它们在管道末端工作得非常好：
#
# 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 }
}
为了能够在我的提示中使用颜色获取时间和路径：
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并修改以适合我的口味，但带有颜色的 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 }
以及一些避免真正重复的过滤任务的捷径：
# 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))
{ $_ }
}

为了从 PowerShell 设置我的 Visual Studio 构建环境，我从这里获取了 VsVars32 。并一直使用它。
################################################# #############################
# 批量暴露环境变量并在此 PS 会话中设置它们
################################################# #############################
函数 Get-Batchfile($file)
{
$theCmd = "`"$file`" & 设置"
cmd /c $theCmd | Foreach-对象 {
$thePath, $theValue = $_.split('=')
Set-Item -path env:$thePath -value $theValue
}
}
################################################# #############################
# 设置这个 PS 会话使用的 VS 变量
################################################# #############################
函数 VsVars32($version = "9.0")
{
$theKey = "HKLM:SOFTWARE\Microsoft\VisualStudio\" + $version
$theVsKey = 获取项目属性 $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"

开始成绩单。这会将您的整个会话写入文本文件。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
这给了我一个在向后滚动时很容易看到的命令之间的分隔线。它还向我显示当前目录，而无需在我正在输入的行上使用水平空间。

我使用了一些功能，因为我是模块作者，所以我通常会加载一个控制台并且迫切需要知道什么在哪里。
write-host "Your modules are..." -ForegroundColor Red
Get-module -li
死硬的书呆子：
function prompt
{
$host.UI.RawUI.WindowTitle = "ShellPower"
# Need to still show the working directory.
#Write-Host "You landed in $PWD"
# Nerd up, yo.
$Str = "Root@The Matrix"
"$str> "
}
强制性的任何我能 PowerShell 我将发挥作用的东西都在这里......
# Explorer command
function Explore
{
param
(
[Parameter(
Position = 0,
ValueFromPipeline = $true,
Mandatory = $true,
HelpMessage = "This is the path to explore..."
)]
[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，所以我确实需要...
Function RDP
{
param
(
[Parameter(
Position = 0,
ValueFromPipeline = $true,
Mandatory = $true,
HelpMessage = "Server Friendly name"
)]
[ValidateNotNullOrEmpty()]
[string]
$server
)
cmdkey /generic:TERMSRV/$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。
Function Lock-RemoteWorkstation
{
param(
$Computername,
$Credential
)
if(!(get-module taskscheduler))
{
Import-Module TaskScheduler
}
New-task -ComputerName $Computername -credential:$Credential |
Add-TaskTrigger -In (New-TimeSpan -Seconds 30) |
Add-TaskAction -Script `
{
$signature = @"
[DllImport("user32.dll", SetLastError = true)]
public static extern bool LockWorkStation();
"@
$LockWorkStation = Add-Type -memberDefinition $signature -name "Win32LockWorkStation" -namespace Win32Functions -passthru
$LockWorkStation::LockWorkStation() | Out-Null
} | Register-ScheduledTask TestTask -ComputerName $Computername -credential:$Credential
}
我也有一个，因为Win+L太远了......
Function llm # Lock Local machine
{
$signature = @"
[DllImport("user32.dll", SetLastError = true)]
public static extern bool LockWorkStation();
"@
$LockWorkStation = Add-Type -memberDefinition $signature -name "Win32LockWorkStation" -namespace Win32Functions -passthru
$LockWorkStation::LockWorkStation() | Out-Null
}
几个过滤器？我认同...
filter FileSizeBelow($size){if($_.length -le $size){ $_ }}
filter FileSizeAbove($size){if($_.Length -ge $size){$_}}
我还有一些我还不能发布，因为它们还没有完成，但它们基本上是一种在会话之间保留凭据而不将它们作为加密文件写出的方法。

您可以在http://github.com/jamesottaway/windowspowershell查看我的 PowerShell 配置文件
如果您使用 Git 将我的 repo 克隆到您的 Documents 文件夹（或 $PROFILE 变量中“WindowsPowerShell”上方的任何文件夹），您将得到我所有的好处。
mainprofile.ps1设置名称Addons为 a的子文件夹PSDrive，然后查找该文件夹下的所有 .ps1 文件进行加载。
我非常喜欢这个go命令，它存储了一个速记位置字典，以便轻松访问。例如，go vsp将带我到C:\Visual Studio 2008\Projects.
我还喜欢覆盖Set-Locationcmdlet 以同时运行Set-Location和Get-ChildItem.
我的另一个最爱是能够在运行后执行mkdirwhich does 。Set-Location xyzNew-Item xyz -Type Directory

我的个人资料是空的。相反，我有脚本文件夹，我可以导航以将功能和别名加载到会话中。一个文件夹将是模块化的，带有函数库和程序集。对于临时工作，我将有一个脚本来加载别名和函数。如果我想处理事件日志，我会导航到文件夹 scripts\eventlogs 并执行
PS > . .\DotSourceThisToLoadSomeHandyEventLogMonitoringFunctions.ps1
我这样做是因为我需要与其他人共享脚本或将它们从一台机器移动到另一台机器。我希望能够复制一个包含脚本和程序集的文件夹，并让它在任何机器上为任何用户工作。
但是你想要一个有趣的技巧集合。这是我的许多“个人资料”所依赖的脚本。它允许调用使用自签名 SSL 的 Web 服务，以便对开发中的 Web 服务进行临时探索。是的，我在我的 powershell 脚本中自由地混合了 C#。
# Using a target web service that requires SSL, but server is self-signed.
# Without this, we'll fail unable to establish trust relationship.
function Set-CertificateValidationCallback

try

好问题。因为我处理几个不同的 PowerShell 主机，所以我在几个配置文件中的每一个都做一些日志记录，只是为了使任何其他消息的上下文更清晰。在profile.ps1，我目前只有那个，但我有时会根据上下文更改它：
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"
}
