Powershell 十个常见任务

学习Powershell的时候，基本的语法也了解了一些，但是就是不知道要写些什么？作为一个过来者，和大家一起分享下常见的几个管理任务脚本。

1.更改本地Administrator账号密码

[ADSI]$Admin = "WinNT://计算机名/用户名"
$Admin.SetPassword(P@ssw0rd)

2.重启或关闭计算机

为了能实现对多台计算机操作，将所有要操作计算机名保存在文本文件中。

Get-Content c:\works\server.txt |

Where-Object {Test-Connection $_ -Quiet -Count 2} |
foreach  {

    Write-Host "restart $_ "-force "Green"
    Restart-Computer $_ -Force -WhatIf
}

3.重启服务

Get-Content c:\works\server.txt | Where-Object {Test-Connection $_ -Quiet -Count 2} |

Invoke-Command {Restart-Service "wuauserv" -PassThru} –ComputerName $_

4.终止进程

Invoke-Command {ps notepad |kill} -ComputerName v-pc

5.打印磁盘信息

function Get-DiskUtil {
    param([string] $computername = $env:COMPUTERNAME)
    process{
        if($_){
            $computername=$_
            }
        gwmi Win32_LogicalDisk -Filter "drivetype = 3" -ComputerName $computername |
        select @{name="Computername";Expression={$_.systemname}},
        deviceID,
        @{Name="SizeGB";expression={"{0:N2}" -f ($_.size/1GB)}},
        @{Name="FreeGB";expression={"{0:N2}" -f ($_.Freespace/1GB)}},
        @{Name="UsedGB";expression={"{0:N2}" -f (($_.size-$_.freespace)/1GB)}},
        @{Name="Perfree";expression={"{0:P2}" -f ($_.Freespace/$_.size)}}
        }
   
}
$data = gc c:\work\server.txt |where {Test-Connection $_ -Quiet -Count 2} |Get-DiskUtil
$data | Sort-Object computername |ConvertTo-Html -Title "DISKUTIL REPORT" -CssUri "c:\sample.css" |Out-File "c:\diskrepot.html"

6.获取近10条错误系统日志

Get-EventLog -LogName System -Newest 10 -EntryType error,warning

Get-EventLog -LogName System -Newest 10 -EntryType error

Get-EventLog -LogName System -Newest 10 -EntryType error | sort source |ft -GroupBy source -Property timewritten,enventid,message

Get-EventLog -logname System -Newest 10 -EntryType error -ComputerName "v-pc1","v-pc2" |sort machinename -Property timewritten,enventid,message

7.文件访问权限

$acl = Get-Acl \\dc\share
$acl.access |where {$_identityrefernce -match "sales"}
Get-Acl \\dc\share |Export-Clixml .\chisales.xml

8.系统启动时间

function Get-Boot {
    param([string]$computername = $env:COMPUTERNAME)
    process{
        if($_){$computername = $_}   
        gwmi Win32_OperatingSystem -ComputerName $computername |
        select @{Name="computername";expression={$_.csname}},
        @{Name="lastboottime";expression={$_.Converttodatetime($_.lastbootuptime)}},
        @{Name="Uptime";expression={(Get-Date) - ($_.Converttodatetime($_.lastbootuptime))}}
        }
}

9.获取系统版本信息

function Get-SP {
    param([string]$computername = $env:COMPUTERNAME)
    process{
        if($_){$computername = $_}
        gwmi Win32_OperatingSystem -ComputerName $computername |
        select  @{Name="computername";expression={$_.csname}},
         @{Name="OperatingSystem";expression={$_.caption}},
         @{Name="SPName";expression={$_.csdversion}},
         @{Name="Version";expression={$_.servicepackmajorversion}}
        }
   
}
