使用powershell从文本文件中的值创建数组

I have a text file with this content:

我有一个包含以下内容的文本文件:

SEGMENTS="worker01 worker02 worker03 worker04"
WORKER_SEGMENTS="worker01 worker02 worker03 worker04"
#SEGMENTS="worker01"
#WORKER_SEGMENTS="worker01"

I read this file from another powershell script and I want to to create an array of the WORKER_SEGMENTS values. I have gotten so far:

我从另一个PowerShell脚本中读取此文件,我想创建一个WORKER_SEGMENTS值的数组。我到目前为止:

$workers = Get-Content $strPath"\worker\conf\segments.conf" | Where-Object {$_ -like "*WORKER_SEGMENTS*"}
Write-Host $workers

This yields:

PS Q:\mles\etl-i_test\rc> .\etl.ps1
WORKER_SEGMENTS="worker01 worker02 worker03 worker04" #WORKER_SEGMENTS="worker01"

I only need the worker01, worker02, worker03, worker04 from WORKER_SEGMENTS (without the leading #) as an array. How do I achieve this?

我只需要WORKER_SEGMENTS中的worker01,worker02,worker03,worker04(没有前导#)作为数组。我该如何实现这一目标?

3 个解决方案

#1

You can try this:

你可以试试这个:

Get-Content .\t.txt | 
? { $_ -like "WORKER_SEGMENTS*" } | 
% { $_ -replace '.*?"([^"]*)".*', '$1' -split " " }

worker01
worker02
worker03
worker04

Get-Content .\t.txt | 
? { $_ -like "WORKER_SEGMENTS*" } | 
% { ($_ -split '"')[1] -split ' ' }

worker01
worker02
worker03
worker04

#2

Try this:

Get-Content $strPath"\worker\conf\segments.conf" | 
    Select-String 'WORKER_SEGMENTS\s*=\s*"([^"]*)"' | 
    Foreach {$_.Matches.Groups[1].Value -split ' '} | 
    Foreach {$ht=@{}}{$ht.$_=$null}
$ht

By using a hashtable we can eliminate duplicate entries fairly easily.

通过使用哈希表,我们可以非常轻松地消除重复的条目。

you may have to tweak it a bit to get exactly what you want, but this should get you headed in the right direction:

你可能需要稍微调整一下才能得到你想要的东西,但这应该让你朝着正确的方向前进:

$workers = (Get-Content $strPath"\worker\conf\segments.conf" | ?{$_ -like 'Worker_Segments*'}).Split('"')[1].Split(' ')
