[PowerShell每日技巧]给对象添加额外的属性标签(20140228)

DAIC

There may be the need to add additional information to command results. Maybe you get data from different machines and want to keep a reference where the data came from. Or, you want to add a date so you know when the data was created.

Tagging objects (adding new columns with additional information) is easy. This will add a new property "SourceComputer" and a date to a service list:

1. Get-Service |
   
2.   Add-Member -MemberType NoteProperty -Name SourceComputer -Value $env:COMPUTERNAME -PassThru |
   
3.   Add-Member -MemberType NoteProperty -Name Date -Value (Get-Date) -PassThru |
   
4.   Select-Object -Property Name, Status, SourceComputer, Date

复制代码

Just remember that your added properties may show up in the result until you use Select-Object and explicitly ask to show them.
