为什么我在Powershell中获得的输出与仅运行代码不同?

为什么我在Powershell中获得的输出与仅运行代码不同?,powershell,start-job,scriptblock,Powershell,Start Job,Scriptblock,在开始作业之外时,脚本可以正常运行,但在脚本块中时,我得到的结果不正确。我哪里做错了 我需要启动作业功能,因为我有远程命令将挂起的服务器(单独的问题-WMI被阻塞),我需要超时并移动到下一个服务器 我已经尝试了在谷歌上找到的每一种变体,但仍然没有我想要的结果 我真的对此束手无策,因为我不明白发生了什么。。。帮忙 谢谢 $timeoutSeconds = 90 ForEach($server in $servers) { #$ErrorActionPreference = "inquir

在脚本块中运行时,我收到错误的日期和KB

SERVERNAME
SERVERNAME,10.1.XX.XX,03/13/2015,KB3022777,True,Microsoft Windows Server 2012 R2 Standard 

vs.

SERVERNAME

为了子孙后代比其他任何事情都重要

我犯的错误是对字符串使用sort对象而不是数值

替换域名和文件路径信息后,以下代码将正常工作

谢谢, -卢克

使用
$lastinstalledOn-gt$lastQFEon
可以比较字符串。最好比较真实的日期,或者让日期字符串的格式正确比较,如
yyyyMMdd
@Theo测试您的建议,结果仍然不匹配。谢谢你的建议。您的比较是正确的。这也适用于您在
$HotFixNumber
上进行的排序。当您通过在
InstalledOn
上排序来获取日期时,您通过在
HotFixID
上排序来检索hotfixNumber(这是一个字符串)。您应该使用相同的排序来获取相同修补程序的编号,否则您可能会在正确的日期得到错误的编号。另外,将
if($lastinstalledOn-gt$null)
更改为
if($lastinstalledOn)
@Theo更安全,谢谢您的建议。我已经更新了该问题以纳入您的修复。但是,输出仍然不同:-(使用
$lastinstalledOn-gt$lastQFEon
您正在比较字符串。最好比较实际日期,或者让日期字符串的格式正确比较,如

@Theo,并与您的建议进行测试,结果仍然不匹配。感谢您的建议。您的比较是正确的。这也适用于在
$HotFixNumber
上进行排序。在

上进行排序以获取日期的同时,在
HotFixID
上进行排序以检索HotFixNumber(这是一个字符串)。您应该使用相同的排序来获取相同修补程序的编号,否则您可能会在正确的日期得到错误的编号。另外,将
