如何读取.txt文件中的文本及其在powershell中的每个值? [英] How to read text in .txt file and each of its value in powershell?

问题描述

我在如下所示的文本文件中有数据，我想使用powershell逐个读取值

I have data in a text file like below, i want to read it value by value using powershell

Name           Enabled Description                                             
----           ------- -----------                                             
administrator1 True                                                            
Azureuser      True    Built-in account for administering the computer/domain  
DefaultAccount False   A user account managed by the system.                   
Guest          False   Built-in account for guest access to the computer/domain

例如，我想在第二个字段中读取名称的值.怎么读?

For example i want to read value for name in 2nd field. How can it be read?

推荐答案

如果没有定界符，则很难进行转换.使用定界符，您可以使用

It is difficult to convert it without having a delimiter in place. With a delimiter you could make use of ConvertFrom-String

如果我们以这种格式使用ConvertFrom-String，它将正确解析前两列，但是描述将用单词分隔.

If we would use ConvertFrom-String with this format, it will parse the first 2 columns correctly, but the description will be seperated in words.

((Get-Content .\test.txt) | ConvertFrom-String -PropertyNames Name, Enabled)

结果:

Name           Enabled P3          P4
----           ------- --          --
Name           Enabled Description
----           ------- -----------
administrator1 True
Azureuser      True    Built-in    account
DefaultAccount False   A           user
Guest          False   Built-in    account

要获得第二个结果，必须考虑标题和分隔符行. 这将返回完整的对象.

To get the second result you have to take in account the header and separator line. This will return the full object.

((Get-Content .\test.txt) | ConvertFrom-String -PropertyNames Name, Enabled)[3]

结果:

Name    : Azureuser
Enabled : True
P3      : Built-in
P4      : account
P5      : for
P6      : administering
P7      : the
P8      : computer/domain

这只会返回已启用"中的值

This will only return the value from "Enabled"

(((Get-Content .\test.txt) | ConvertFrom-String -PropertyNames Name, Enabled)[3]).Enabled

结果:

True
