若想要將PowerShell在此session中的所有執行過程以及執行結果(就是畫面上所有的東西)紀錄到某個檔案中,我們可以使用

PS C:\>Start-Transcript -path 檔案路徑

若欲結束紀錄則使用

• 12 Cool Features of Windows PowerShell
1. Built-in Cmdlets (pronounced "commandlets") for Managing Windows
2. The power of wildcards and working objects
3. Whatif you could test your commands before committing to them
   • PS> stop-service w3* -whatif
4. Take a transcript
   • PS> Start-Transcript -Path c:\demo\dfoshow.txt
     PS> Stop-Transcript
5. Make Windows talk from the command line
   • PS> $spVoice = new-object -com "SAPI.spvoice"

About Windows PowerShell

• PS C:\> set-location Data
• PS C:\Data> get-childitem Pow*
• PS C:\Data> copy-item 'PowerShell' 'C:\Data\PSBackup' -recurse -force
• 複製PowerShell資料夾及其底下所有的檔案與資料夾
• PS C:\Data> remove-item PSBackup
• 刪除PSBackup 資料夾及其底下所有的檔案與資料夾
• PS C:\Data> get-content 'Hello.txt' | out-file '.\HelloCopy.txt'
• PS C:\Data> get-content HelloCopy.txt
• the get-content cmdlet is roughly equivalent to the type (Windows) or cat (Unix) commands
• PS C:\Data> sl \
• 使用set-location的alias sl 將目前路徑改為C:\
• 查看sl為何者的alias
• PS C:\> get-alias sl

一般情形下所設定的alias 其存續期間僅在此session內
因此關掉視窗之後alias則不存在
若想要保留此alias則需將其設定於Profile檔
<註>自行建立的function,variable也是如此

• 用PowerShell寫Event Log
• $a = new-object -type system.diagnostics.eventlog -argumentlist system   #寫到事件紀錄器的系統中
• $a.source = "Windows PowerShell Week"  #事件來源
• $a.writeentry("This is just a test.","Information") #前者為事件內容 後者為事件的種類(包含 Error,FailureAudit,Information,SuccessAudit,Warning)
• 一個source只能連結一種事件(應用程式,系統,安全性)
• Remote Computer
• $a = new-object -type system.diagnostics.eventlog -argumentlist system,ComputerName
• PowerShell Formating Files
• 一樣的get-process 得到不同的output
• $PSHOME中的dotnettypes.format.ps1xml
• 
• <View>
      <Name>process</Name>
          <ViewSelectedBy>
            <TypeName>.NET Class Name</TypeName>
          </ViewSelectedBy>.....
• System.Diagnostics.Process
• <View>
  

• 將1,2,3,4,5儲存於變數中,$a即為陣列
  PS C:\> $a =1,2,3,4,5
  
• 顯示陣列元素個數
  PS C:\> $a.Length
  

所需執行的指令如果是會變動的(可能透過程式動態組合出的指令字串)如
"get-process " + "| sort-object  CPU -desc  " + " |select-object -first 3"
則我們可以透過Invoke-Expression指令執行之

上述三個字串分別代表

PS C:\>get-command

執行後畫面一直捲動 直到最後一筆
正常人應該無法一眼看完

• 執行 PowerShell Script
  
  
  
  

• 0.Object
• object has..
• Unique name
• Properties
• Methods
• Like command tool
• unique name
• Let you do things
• group together related functionality
• Can be used from command prompt
• Like output strings
• Contain results
• Can be parsed for particular bits of info
• Can be used from command prompt
• Type of object
• COM obj
• WMI obj
• .NET framework obj
• Windows powerShell obj
• 1.Using Object
• COM
• $obj = new-object -comobject <PROGID>
• $obj = new-object -com <PROGID>
• PROGID look like "WScript.Network" and they stored in the registry HKEY_CLASSES_ROOT
• Accessing Properties
• $obj = new-object -com WScript.Network
• $obj.Name
• Setting Properties
• $ExcelObj = new-object -com Excel.Application
• $ExcelObj.Visible = $true
• $WorkBookObj =  $ExcelObj.Workbooks.add()
• $WorkSheetObj  = $WorkBookObj.Worksheets.Item(1)
• $WorkSheetObj.Cells.Item(1.1) = "Feel the Power"
• $ExcelObj.Quit
• Calling Methods
• $WorkBookObj =  $ExcelObj.Workbooks.add()
• WMI
• $obj = get-wmiobject -class <WMI Class>
• $obj = get-wmiobject <WMI Class>
• $obj = get-wmiobject -query <WQL>
• Accessing Properties
• $obj = get-wmiobject win32_process
• $obj.WorkingSetSize
• $obj | foreach-obkect {$_.ProcessName +":"+$_.WorkingSetSize}
• Modifying Properties
• $wmi_settings = get-wmiobject win32_wmisetting
• $wmi_settings.ASPScriptDefaultNamespace = "root\default"
• Calling methods
• $obj = get-wmiobject win32_process -filter 'Name = "notepad.exe"'
• $obj.GetOwner()
• .NET framework
• $obj = new-object -typeName <Fully-Qualified Name>
• $obj = new-object <Fully-Qualified Name>
• $obj = [ADSI]"LDAP://localhist:389/dc=NA,dc=fabrikam,dc=com"
• $di = new-object System.IO.DiretoryInfo($PSHOME)
• $PSHOME : home dir for PowerShell
• Accessing Properties
• $di = new-object System.IO.DiretoryInfo($PSHOME)
• $di.CreationTime
• Calling methods
• $di.CreateSubdirectory("test")
• $web = new-object System.Net.WebClient
• $page = $web.downloadstring(http://www.scriptingguys.com)\
• UI
• [System.Refleciotn.Assembly]::LoadWithPartialName(" System.windows.Forms")
• $form = new-object System.Wondows.Forms.form
• 2.Exploring Object
• get-member
• OLEView
• Go to MSDN library
• $objshell = get-object -com "Shell.Application" | get-member
• $objFilder = $objshell.BrowseForFolder(0,"Pick Me!!",0)  //跳出瀏覽資料夾視窗
• System.IO.DirectoryInfo  //namespace
• $di = get-member -membertype Property
• 3.Displaying Object
• Many ways to "display" an object
• Windows PowerShell provides a default way
• XML config files let you change that default
• 修改types.ps1xml檔以修改預設顯示欄位
• $PSHOME\types.ps1xml
• ... | format -list *
• set-executionpolicy remotesigned
• update-typedata
• 4.Saving and Restoring Object
• Export-Clixml saves a representation of the object to a file you can revive later
• new-object -com "WScript.Network" | export-clixml "mothball.xml"
• Import-Clixml restores the object from a file
• $obj = import-clixml "mothball.xml"
• 5.Copying and Modifying Object
• Select-Object
• Creates a new object by copying a portion of an exising one 
• Add-Member
• Augments an object by adding to an existing one
• Add property using select-object
• get-process | select-object ProcessName,@{Name="Start Day";Expression = {$_.startTime.DayofWeek}}
• 上述物件型態:System.management.automation.PSCustomObject
• Add property using add-mamber
• $a = "thanks for watching windows powershell week"
• $a = add-member -inputobject $a -membertype scriptmethod -name words -value {$this.splite()} -passthru
• 6.Comparing Object
• compare-object
• $process = get-process
• notepad
• $processes_now = get-process
• compare-object -ref $process -dif $process_now
• $process_now | where-object {$_.Name -eq 'notepad'} | select-object Name,HasExited  //true

• , $procs | get-member  //object[ ]

• Reflection uses Get-Member
• Simple,consistent,and use dot notation
