首先,我只是在学习 PowerShell,但我已经使用多种脚本语言进行了编程。
我正在编写一个脚本来从远程服务器上的命令中检索输出,然后检查该输出中是否存在“运行”一词。现在它检索命令的输出,我把它放在我的变量中,$data
. 问题是我将它放在我的“clean_data”函数中,并且它与我传递给函数的变量中的内容不同。
我想知道的是,$data
变量的输出在打印到屏幕时究竟如何具有一个内容,但是当传递给一个函数并立即打印时有一个新的内容?我错过了什么?
我只想遍历返回的行以查看其中有多少“正在运行”,如果没有则打印一个很好的错误。
CODE(部分:功能及相关代码)
function clean_data($input) {
Write-Output "Received data"$input
Write-Output "Cleaning data"
$output=@()
foreach ($line in $input) {
Write-Output "Looking at: "$line.ToString()
if ($line.ToString().Contains("running")) {
$output+=$line
}
}
Write-Output $output
return ,$output
}
$data = Get-Job -id $jobid.id | Receive-Job
Write-output "Data Type: "$data.GetType().Fullname
Write-Output "Output of $cmd"
