你的PowerShell`profile.ps1`文件中有什么？

Question

您的个人资料中包含哪些基本内容(功能,别名,启动脚本)？

Answer 1

我经常发现自己需要一些基本的agregates来计算/总结一些东西.我已经定义了这些函数并经常使用它们,它们在管道的末尾非常好地工作:

#
# 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获得颜色的时间和路径:

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并修改以符合我的口味,但颜色的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 }

还有一些快捷方式可以避免重复的过滤任务:

# 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))
        { $_ }
}

Answer 2

要从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.

###############################################################################
# Exposes the environment vars in a batch and sets them in this PS session
###############################################################################
function Get-Batchfile($file) 
{
    $theCmd = "`"$file`" & set" 
    cmd /c $theCmd | Foreach-Object {
        $thePath, $theValue = $_.split('=')
        Set-Item -path env:$thePath -value $theValue
    }
}


###############################################################################
# Sets the VS variables for this PS session to use
###############################################################################
function 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, "Tools")
    $theBatchFile = [System.IO.Path]::Combine($theVsToolsDir, "vsvars32.bat")
    Get-Batchfile $theBatchFile
    [System.Console]::Title = "Visual Studio " + $version + " Windows Powershell"
}

Answer 3

这将遍历脚本PSDrive并点源所有以"lib-"开头的内容.

### ---------------------------------------------------------------------------
### Load function / filter definition library
### ---------------------------------------------------------------------------

    Get-ChildItem scripts:\lib-*.ps1 | % { 
      . $_
      write-host "Loading library file:`t$($_.name)"
    }

Answer 4

开始成绩单.这会将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.

Answer 5

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

这给了我一个命令之间的分隔符,当滚动回来时很容易看到.它还向我显示当前目录,而不使用我正在键入的行上的水平空格.

例如:

C:\ Users\Jay -------------------------------------------- -------------------------------------------------- ------------

Answer 7

我摇滚一些功能,因为我是模块作者,我通常加载一个控制台,迫切需要知道它在哪里.

write-host "Your modules are..." -ForegroundColor Red
Get-module -li

死硬的神经:

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> "
}

强制性的任何我可以PowerShell我将功能去这里...

# 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
}

有时我想启动资源管理器作为登录用户以外的人...

# 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
}

我也有一个给我,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
}

一些过滤器？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帖,因为它们没有完成,但它们基本上是一种在会话之间保留凭据而不将其作为加密文件写出来的方法.

我保留了一切.大多数情况下,我的配置文件设置了所有环境(包括调用脚本来设置我的.NET/VS和Java开发环境).

我还prompt()使用自己的样式重新定义了该函数(请参阅其中的操作),为其他脚本和命令设置了几个别名.并改变$HOME指向的内容.

这是我完整的个人资料脚本.
