我有一个PowerShell脚本 StartWatching.ps1 ,它使用FileSystemWatcher监视文件夹:
### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\ScheduledTasks\PlanUpdates"
$watcher.Filter = "*.sql"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true
### DEFINE ACTIONS AFTER A EVENT IS DETECTED
$action = {
$path = $Event.SourceEventArgs.FullPath
$changeType = $Event.SourceEventArgs.ChangeType
$logline = "$(Get-Date), Processed, $path"
Add-content "C:\ScheduledTasks\PlanUpdates\log.txt" -value $logline
cmd.exe /c 'C:\ScheduledTasks\PlanUpdates\planUpdate.bat'
}
### DECIDE WHICH EVENTS SHOULD BE WATCHED + SET CHECK FREQUENCY
$created = Register-ObjectEvent $watcher "Created" -Action $action
while ($true) {sleep 1}
只要在文件夹中创建.sql文件,脚本就会启动.bat文件 planUpdate.bat 。 .bat文件执行特定SQL服务器上的.sql文件的内容(数据库在.sql文件中声明),然后将文件移动到子文件夹“Old”:
for %%f in (.\*.sql) do sqlcmd -S <server> -i %%f & move "%%f" .\Old
当我通过右键单击并选择“使用PowerShell运行”启动PowerShell脚本时,它可以完美运行。
我需要在从cmd执行脚本之前使其工作,然后才能作为计划任务。但是当我从cmd启动它时,它不起作用:
powershell -noexit -file C:\ScheduledTasks\PlanUpdates\StartWatching.ps1
它打开一个命令窗口,就像脚本正在运行一样,但FileSystemWatcher没有注册任何事件
我希望你可以提供帮助,因为我一整天都试图解决这个问题。

我遇到了同样的问题。
我不知道为什么会有效,但请尝试更改
powershell -noexit -file C:\ScheduledTasks\PlanUpdates\StartWatching.ps1
到
powershell -noexit -file ". C:\ScheduledTasks\PlanUpdates\StartWatching.ps1"
