Get-EventLog
 
大纲
取得本地事件日志的信息或存储在事件日志记录中的项.
 
语法
Get-EventLog [-logName] <string> [-newest <int>] [<CommonParameters>]
 
Get-EventLog [-list] [-asString] [<CommonParameters>]
 
详细描述
取得本地事件日志的信息或存储在事件日志记录中的项.
 
参数
 
-logName <string>
指定取得事件的日志文件名.
 
强制参数?
true
参数位置?
1
默认值
 
允许从管道绑定输入?
false
允许通配符扩展?
false
 
-list <SwitchParameter>
返回事件日志列表, 而不是指定日志中的项.
 
强制参数?
false
参数位置?
named
默认值
 
允许从管道绑定输入?
false
允许通配符扩展?
false
 
-asString <SwitchParameter>
将输出作为字符串而不是对象发送.
 
强制参数?
false
参数位置?
named
默认值
 
允许从管道绑定输入?
false
允许通配符扩展?
false
 
-newest <int>
取得最新的 'N' 条事件日志项, 数值 'N' 表示事件日志中最新的条数.
 
事件日志中通常包含上万条甚至更多的事件日志项, 因此考虑使用参数-Newest限制返回的项数.
 
强制参数?
false
参数位置?
named
默认值
 
允许从管道绑定输入?
false
允许通配符扩展?
false
 
<公共参数>
此命令支持公共参数: -Verbose, -Debug, -ErrorAction, -ErrorVariable, and -OutVariable. 更多信息, 输入, "get-help about_commonparameters".
 
输入类型
None
 
返回类型
Object, String
 
注意
 
事件的EventID属性是由System.Diagnostics.EventLogEntry.EventID 的两个低字节构成. Windows PowerShell定义了一个名为EventID的脚本属性, 此属性将会复写原有的EventID属性并返回该值的两个低字节. 你可以使用get-EventID()方法取得原始的EventID属性值.
 
更多信息, 输入"Get-Help Get-EventLog  -detailed". 需要技术信息, 输入"Get-Help Get-EventLog -full".
 
如果需要为该命令提供多个参数, 请使用逗号进行分隔. 例如, "<parameter-name> <value1>, <value2>".
 
1
 
C:/PS>get-eventlog -list
 
此命令显示计算机上的事件日志信息(列表).
 
2
 
C:/PS>get-eventlog -newest 5 -logname application
 
此命令显示应用程序事件日志中最近的5.
 
3
 
C:/PS>$events = get-eventlog -logname system -newest 1000
$events | group-object eventid
 
此命令返回系统事件日志中最近的1000, 并将它们存储在变量$events. 结果通过管道发送给Group-Object cmdlet, 后者根据时间ID对它们进行分组.

### PowerShell 命令列表及功能解释 以下是一些常用的 PowerShell 命令及其功能的详细说明: #### 1. 获取帮助信息 `Get-Help` 是用于获取命令或主题帮助信息的工具。通过此命令,用户可以了解特定命令的用法、参数和示例。 ```powershell Get-Help Get-Process ``` 上述命令将显示 `Get-Process` 的基本帮助信息[^1]。若需要更详细的帮助信息,可以添加 `-Detailed` 参数: ```powershell Get-Help Get-Process -Detailed ``` #### 2. 列出所有别名 PowerShell 提供了丰富的别名功能,可以通过以下命令查看当前会话中所有命令的别名: ```powershell Get-Alias ``` 此命令将列出所有可用的别名及其对应的完整命令名称[^1]。 #### 3. 管理进程 `Get-Process` 用于检索系统上运行的所有进程信息。例如: ```powershell Get-Process ``` 如果需要停止某个特定进程,可以使用 `Stop-Process` 命令: ```powershell Stop-Process -Name notepad ``` 上述命令将终止名为 `notepad` 的进程。 #### 4. 文件与目录操作 `Get-ChildItem` 用于列出指定路径下的文件和子目录。例如: ```powershell Get-ChildItem C:\Users\Username\Documents ``` 若需要递归地列出所有子目录中的内容,可以添加 `-Recurse` 参数: ```powershell Get-ChildItem C:\Users\Username\Documents -Recurse ``` #### 5. 管理服务 `Get-Service` 用于检索系统上的服务信息。例如: ```powershell Get-Service ``` 若需要启动或停止某个服务,可以分别使用 `Start-Service` 和 `Stop-Service` 命令: ```powershell Start-Service -Name Spooler Stop-Service -Name Spooler ``` #### 6. 管理事件日志 `Get-EventLog` 用于检索系统事件日志中的条目。例如: ```powershell Get-EventLog -LogName System -Newest 10 ``` 上述命令将显示系统日志中最新的 10 条记录。 #### 7. 远程管理 `Enter-PSSession` 用于建立与远程计算机的交互式会话。例如: ```powershell Enter-PSSession -ComputerName RemotePC ``` 若需要执行单个命令而不进入交互模式,可以使用 `Invoke-Command`: ```powershell Invoke-Command -ComputerName RemotePC -ScriptBlock { Get-Process } ``` #### 8. 网络配置 `Get-NetIPAddress` 用于检索网络接口的 IP 地址配置。例如: ```powershell Get-NetIPAddress ``` 若需要更改 IP 地址配置,可以使用 `New-NetIPAddress` 或 `Set-NetIPAddress` 命令。 #### 9. 注册表管理 `Get-ItemProperty` 用于检索注册表项的属性值。例如: ```powershell Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion" ``` #### 10. 执行脚本 可以通过 `Invoke-Expression` 或直接调用脚本来执行 PowerShell 脚本。例如: ```powershell .\script.ps1 ``` --- ### 示例代码 以下是一个综合示例,展示如何使用多个 PowerShell 命令完成任务: ```powershell # 获取所有正在运行的进程,并将其名称保存到文件中 (Get-Process | Select-Object -ExpandProperty Name) > process_list.txt # 查看当前用户的文档目录下所有文件的大小 Get-ChildItem -Path "$env:USERPROFILE\Documents" -File | Format-Table Name, Length -AutoSize # 停止名为 'notepad' 的进程 Stop-Process -Name notepad ``` --- ###
