3.运行脚本

描述：脚本和批处理都属于伪可执行文件，它们只是包含了若干命令行解释器能够解释和执行的命令行代码。

# 1.执行批处理文件：批处理是扩展名为”.bat”的文本文件，它可以包含任何cmd控制台能够处理的命令
PS C:\PS> ./ping  #实际执行ping.bat
batch File Test
Press any key to continue . . .
 Volume in drive C has no label.
 Volume Serial Number is 4E9B-D846


# 2.执行VB脚本文件,执行.\test.vbs 会遍历当前Win32进程，并把每个进程的详细信息通过窗口显示出来。
Set wmi = GetObject("winmgmts:")
Set collection = wmi.ExecQuery("select * from Win32_Process")
For Each process in collection
WScript.Echo process.getObjectText_
Next

PS C:\PS> cscript.exe .test.vbs #PS执行VB脚本


# 3.执行powershell脚本扩展名为“.ps1”
PS C:\PS> echo "dir;Get-PSProvider;help dir" >test.ps1
PS C:\PS> Get-Content ./test.ps1
dir;Get-PSProvider;help dir
PS C:\PS> ./test.ps1

注意事项:

初次执行PS1脚本时可能会碰到一个异常,由于默认安全设置禁用了执行脚本，要启用这个功能需要拥有管理员的权限。

$C = Get-Culture | Select-Object -Property *

@{TestKey = (‘x’ * 200)} | Out-String -Width 250

PS C:\Users\WeiyiGeek> Get-Command -Name *Printer

CommandType Name Version Source

Function Add-Printer 1.1 PrintManagement
Function Get-Printer 1.1 PrintManagement
Function Remove-Printer 1.1 PrintManagement
Function Rename-Printer 1.1 PrintManagement
Function Set-Printer 1.1 PrintManagement
Cmdlet Out-Printer 3.1.0.0 Microsoft.PowerShell.Utility

选择对象的属性

包含在每一个对象中的属性可能有很多，但是并不是所有的属性你都感兴趣，这时可以使用Select-Object 限制对象的属性。接下来的例子演示如果获取机器上匿名帐号的完整信息。

PS C:Usersv-bali.FAREAST> Get-WmiObject Win32_UserAccount -filter “LocalAccount=True AND Name=’guest’”

AccountType : 512
Caption : myhomeguest
Domain : myhome
SID : S-1-5-21-3064017030-3269374297-2491181182-501
FullName :
Name : guest

如果你只对用户名、描述，启用感兴趣。

PS C:Powershell> Get-WmiObject Win32_UserAccount -filter “LocalAccount=True AND
Name=’guest’” | Select-Object Name,Description,Disabled

Name Description Disabled

guest Built-in account for gu… True

#使用比较运算符”like”过滤当前应用的数组, 这里可以用比较运算符结合控制台命令匹配出所有条件。
@(ipconfig /all) -like “IPV4“
pageid: 327
IPv4 地址 . . . . . . . . . . . . : 192.168.1.88(首选)

参数

PS编程之命令行参数传递与绑定:

方法1:$args 参数位置传值法它实际是一个对象数组，注意输入参数的位置是固定的并且$args[0]表示命令中输入的第一个参数并非脚本名称(与Bash Shell有区别)

# args.ps1 文件内容
Write-Host $args[0] 
Write-Host $args[1]
Write-Host $args[2] 
Write-Host "命令行:$args"  #注意在""之中 $args[0] 加入没有任何意义，它只会解析$args 数组;
Write-Host -noNewLine "命令行:" $args[0] $args[1] $args[2]

#执行
$args.ps1 1  "参数2"  param3

#执行结果
1
参数2
param3
命令行:1 参数2 param3
命令行:1 参数2 param3

方法2:CmdletBinding 脚本内部变量名,适合于传递多个参数值可以指定参数名称，并且参数值的位置随机。

# DeployBuildEnv.ps1 文件内容
[CmdletBinding()]
Param (
  [string] $Name = "",
  [Int32] $Age = 0,
  [string] $Gender = "未知"
)

$arg = $Name + " - " + $age + " - " + $Gender;
Write-Host $arg
Write-Host "命令行绑定: $arg"


#执行
.\DeployBuildEnv.ps1 -Name WeiyiGeek -Age 20 -Gender 男

#执行结果
WeiyiGeek - 20 - 男
命令行绑定: WeiyiGeek - 20 - 男

注意事项:

#必须放在脚本最上面否则报错CmdletBinding
PS命令行支持：单引号，双引号，中文的单引号，中文的双引号 ,以及中文变量名，中文参数名(linux版的powershell也完全支持)。

模块查找与安装:
Tips:没有该find-module模块的点击，注意需要以管理员权限运行;

# 模块查找
find-module *ssh*
# Version    Name                                Repository           Description

# 0.0.3      dockeraccesshelper                  PSGallery            Allow a user account to access the docker engine without elevated access rights

# 安装Posh-SSH的模块
Install-Module Posh-SSH
# 你正在从不受信任的存储库安装模块。如果你信任该存储库，请通过运行 Set-PSRepository cmdlet 更改其 InstallationPolicy
# 值。是否确实要从“PSGallery”安装模块?
[Y] 是(Y)  [A] 全是(A)  [N] 否(N)  [L] 全否(L)  [S] 暂停(S)  [?] 帮助 (默认值为“N”): y

# 删除模块
# 删除Posh-SSH的目录：C:\Program Files\WindowsPowerShell\Modules\Posh-SSH
remove-module -name posh-ssh -Force -Verbose -Debug

#查看模块命令
get-command -Module posh-ssh

在PowerShell中如何检测模块是否存在

我们可以使用Get-Module的另一个参数-ListAvailable来列出是否含有潜在的模块。
Get-Module -ListAvailable -Name Azure

Powershell检测网络中存活地址

# 方式1 
for($i=1; $i -le 255; $i++){
  ping -n 3 10.0.0.$i >> Paddr.txt
}

# 方式2
$Ping = New-Object system.net.networkinformation.ping 
1..253 | % { $Ping.send( "192.168.12.$_" ) | select address,status} | Out-File -FilePath IPaddr.txt -Encoding utf8
$IP = Get-Content "IPaddr.txt" | Where-Object { $_ -match "Success" } 
-split $IP | Where-Object { $_  -like  "192*" } |  Out-File -FilePath IP-Successful.txt -Encoding utf8



$hostname = foreach ( $i  in  $IPS ) { [System.Net.DNS]::GetHostByAddress($i).HostName;$i}
$hostname 


 [System.Net.DNS]::GetHostName() 

 [System.Net.DNS]::GetHostAddresses("192.168.12.188") 

188..199 | % { [System.Net.DNS]::GetHostEntry("192.168.12.194").HostName; }
