Question

我有一个变量$gh，其输出如下。我的意思是我输入$gh时。我将获得如下所示的值。

PS C:\Windows\system32>$gh

No.  Department Name          Environment Id           Location Name   Ready Status          Machine Pure Status   
1    EMA-MET-CAT5-KY04        Environment-k2345             EMA               Enabled                  GREEN         
2    EMA-MET-CAT5-KY03        Environment-k89               EMA               Enabled                  GREEN         
3    EMA-EFT-JIU-FC           Environment-k3456             EMA               Enabled                  GREEN         
4    EMA-MET-CAT5-KY08        Environment-k7890             EMA               Not Ready                UNKNOWN       
5    EMA-MET-CAT5-KY02-ED      Environment-k9                EMA               Enabled                  GREEN

$gh的类型为System.String，$gh.GetType().fullname的类型。

我想将部门名称和环境ID中的值放入数组或变量中，以便在查询EMA-MET-CAT5-KY08时可以获取环境ID Environment-k7890。

Answer 1

假设部门名称和环境ID中没有空格，我将使用正则表达式（regex）在一行的开头查找模式（数字，空格，名称，空格，id）并将其放入哈希表。

PS C:\> $lookup = @{}
PS C:\> [regex]::matches($gh, '(?m)^\d+\s+([^\s]+)\s+([^\s]+)').foreach{
    $lookup[$_.groups[1].value] = $_.groups[2].value
}
PS C:\> $lookup

Name                           Value
----                           -----
EMA-EFT-JIU-FC                 Environment-k3456
EMA-MET-CAT5-KY02-ED           Environment-k9
EMA-MET-CAT5-KY04              Environment-k2345
EMA-MET-CAT5-KY03              Environment-k89
EMA-MET-CAT5-KY08              Environment-k7890


PS C:\> $lookup['EMA-MET-CAT5-KY08']
Environment-k7890

Answer 2

另一种方法是将表拆分为列
通过用逗号替换两个或多个空格
如果标题正确，则可以ConvertFrom-Csv和
Select-Object所需属性

$gh = "No.  Department Name          Environment Id           Location Name   Ready Status          Machine Pure Status   
1    EMA-MET-CAT5-KY04        Environment-k2345             EMA               Enabled                  GREEN         
2    EMA-MET-CAT5-KY03        Environment-k89               EMA               Enabled                  GREEN         
3    EMA-EFT-JIU-FC           Environment-k3456             EMA               Enabled                  GREEN         
4    EMA-MET-CAT5-KY08        Environment-k7890             EMA               Not Ready                UNKNOWN       
5    EMA-MET-CAT5-KY02-ED      Environment-k9                EMA               Enabled                  GREEN        
"

$Data = $gh -split [environment]::newline | ForEach-Object {
    $_ -replace ' {2,}',','
} | ConvertFrom-csv | Select-Object "Department Name","Environment Id"

$Data | Where-Object 'Department Name' -eq 'EMA-MET-CAT5-KY08'

示例输出：

Department Name   Environment Id
---------------   --------------
EMA-MET-CAT5-KY08 Environment-k7890

从类型为system.string的变量中读取值
