[英]Powershell - Array Loop for service start and copy files
我需要有關 Powershell 特定問題的幫助。
我想要做的是逐一啟動多個服務,並在成功啟動過程后,我需要將一些文件從一個位置復制到另一個位置。 這些文件僅在服務/應用程序啟動后創建。 我需要從文本文件中的字符串中檢查它(如“服務已成功啟動”)。
我試圖做一個 for-each 循環,但由於復制和文本檢查位置不同,我無法做到。 老實說,我沒有太多關於嵌套循環的信息。 也許你可以給我一些想法來完成這項工作。
例如,對於 1 個服務;
C:\\sourcepath\\location1\\folder\\abc.dat
C:\\sourcepath\\location1\\folder\\cde.dat
C:\\sourcepath\\folder1\\logs\\logfile.txt
---流程應該是這樣的;
甚至任何方向都會有所幫助。
編輯1:
到目前為止,我可以編寫代碼。
[array]$serviceNames = "lfsvc", "iphlpsvc"
[array]$app = "app1", "app2"
$sourceStart = "C:\Source\"
$destinationStart = "C:\Target\"
$logs = "\logs"
$sourceFull = $sourceStart+$app.Get(0)+"\data"
$destinationFull = $destinationStart+$app.Get(0)
ForEach ($serviceNames in $serviceNames)
{
Start-Service $serviceNames -ErrorAction SilentlyContinue;
$text = Select-String -Path $sourceStart+$app.Get(0)+$logs\log.txt -Pattern "Service successfully started"
if ($text -ne $null)
{
md $destination;
Copy-Item -Path $sourceFull\123.txt -Destination $destinationFull\123.txt
Copy-Item -Path $sourceFull\456.txt -Destination $destinationFull\456.txt
}
}
謝謝
Edit2:如果我想用很長的方式寫它,那應該是這樣的。 (Ofc,如果我可以從指定的文本文件中檢查字符串,它將是 gr8)
我需要縮短代碼
[array]$serviceNames = "aService", "bService"
Start-Service $serviceNames[0] -ErrorAction SilentlyContinue;
Start-Sleep -Seconds 75;
md "C:\Dest\aService\fld";
Copy-Item -Path "C:\Source\aService\fld\123.txt" -Destination "C:\Dest\aService\fld\123.txt";
Copy-Item -Path "C:\Source\aService\fld\456.txt" -Destination "C:\Dest\aService\fld\456.txt";
Copy-Item -Path "C:\Source\aService\fld\789.txt" -Destination "C:\Dest\aService\fld\789.txt";
Stop-Service $serviceNames[0] -ErrorAction SilentlyContinue;
Start-Sleep -Seconds 15;
Start-Service $serviceNames[1] -ErrorAction SilentlyContinue;
Start-Sleep -Seconds 75;
md "C:\Dest\bService\fld";
Copy-Item -Path "C:\Source\bService\fld\123.txt" -Destination "C:\Dest\bService\fld\123.txt";
Copy-Item -Path "C:\Source\bService\fld\456.txt" -Destination "C:\Dest\bService\fld\456.txt";
Copy-Item -Path "C:\Source\bService\fld\789.txt" -Destination "C:\Dest\bService\fld\789.txt";
Stop-Service $serviceNames[1] -ErrorAction SilentlyContinue;
Start-Sleep -Seconds 15;
我想我知道你想要什么。
[array]$serviceNames = "lfsvc", "iphlpsvc"
[array]$apps = "app1", "app2"
$sourceStart = "C:\Source\"
$destinationStart = "C:\Target\"
$logs = "\logs"
# main loop, which loops over the apps
foreach($app in $apps)
{
$sourceFull = $sourceStart + $app + "\data"
$destinationFull = $destinationStart + $app
# each app will iterate over all of the services
ForEach ($name in $serviceNames)
{
# uses -passthru to get the service object, and pulls its status from that. Will cause any errors to terminate the script
$status = (Start-Service $name -ErrorAction Stop -PassThru).Status
# this while loop will cause it to pause until the service is in "running" state
while($status -ne "Running") {Start-Sleep -Seconds 5; Get-Service $name}
$text = Select-String -Path $($sourceStart + $app + $logs + "\log.txt") -Pattern "Service successfully started"
# check to see if the $text variable is null or empty, if not, do the thing
if (![string]::IsNullOrEmpty($text))
{
if(!(Test-Path -Path $destinationFull)){New-Item -ItemType Directory -Path $destinationFull}
Get-Content -Path "$sourceFull\123.txt" | Add-Content -Path "$destinationFull\123.txt"
Get-Content -Path "$sourceFull\456.txt" | Add-Content -Path "$destinationFull\456.txt"
}
# stops the service
$status = Stop-Service $name -PassThru
# pauses until the service is stopped
while($status -ne "Stopped") {Start-Sleep -Seconds 5; Get-Service $name}
}
}
像這樣的東西?
