我已经知道如何使用任务列表来测试特定软件实例是否正在运行。
@echo off 标题 - FTView 客户端应用程序查找器
任务列表 /FI “WINDOWTITLE EQ Grain*”
我收到的回复类似如下。
图像名称 PID 会话名称 会话＃ 内存使用情况 =========================== ======== ================ ============ ============ DisplayClient.exe 3768 控制台 4 62,476 K
如果找不到应用程序，有没有办法使用此信息来启动它？
我的目的是创建一个计划任务，每 15-30 分钟运行一次，以运行批处理文件，该文件将查找此特定软件实例并启动该软件（如果尚未运行）。我无法使用任务图像名称，因为此计算机上运行着同一软件的多个实例，所以我必须查找特定实例。
在 Damian L. 的帮助下，我使用 Powershell 而不是命令行取得了一些进展。在第 17 行（第二个 Else）仍然有一个问题，脚本启动了请求的应用程序，但没有正确设置 $LoggingResult 变量。它只是输出最后一个已知的 $LoggingResult。
#Script Looks for FTView Logging Application
#If Found - Logs that the application is Running to the Log Text File
#If Not Found - Launches the production logging client and Logs appropriate message to the Log Text File
#If Multiple Instances are found - Notifies the operator to close one down.
$Time = Get-Date #variable for the current date string
$Logfile = [string] 'c:\Shared Folder\LoggerLaunchLog.txt' #variable Log File Path
$WindowLookup = [string] 'Grain*' #variable for what window title you are looking for.
$TargetApp = [string]'C:\Users\Public\Documents\RSView Enterprise\SE\Client\GGCLA-WWMill.cli' #Variable for defining the application to launch
#
#
$process = Get-Process | Where-Object -Like MainWindowTitle -Value $windowlookup #Looks for running process with matching window title
#evaluation & action depending on result
If ($process.count -gt 0){
If ($process.count -gt 1) {$LoggingResult = "Multiple Instances of Logging Application Are Running - Please Close 1"}
else {$LoggingResult = "Logging Application is Running"}
}
else {Start-Process $TargetApp{$LoggingResult = "Logging Application not found - Loading Application"}}
Write-Output "$Time $LoggingResult" #Command Line output for Powershell Visual display - optional
Add-content $Logfile -value "$Time $LoggingResult" #Writes the results & actions to the Log Text File
#pause #for testing to visually see output
最后编辑 - 再次感谢 Damian T. 的帮助，现在一切正常......

答案1
老实说，对于这种性质的事情，我建议改用 PowerShell。PS v5.1 可以安装在 Windows 7（包括 7）之后的任何系统上。
但是，如果您只能使用基本命令提示符，这里有一个可以使用的示例批处理文件。
批
@echo off
:: Title - FTView Client Application Finder
:: This what is said if it's not running
set TESTSTR=INFO: No tasks are running which match the specified criteria.
set /A NOTRUNNING=0
:: Iterate over all of the lines produced by the command.
for /F "delims=" %%a in ('tasklist /fi "WINDOWTITLE EQ Grain*"') do (
:: If a line matches the test string, then the program isn't running.
if "%%a"=="%TESTSTR%" (
set /A NOTRUNNING=1
)
)
if %NOTRUNNING%==1 (
echo It is NOT running.
) else (
echo It is running.
)

但是，PowerShell 的功能更加广泛。其优点包括：
- 更严格的标准以匹配所需的工艺
- 执行流程的更多选项
- 更好的错误处理
- 更好的流量控制
由于我没有您想要匹配的程序，因此我很难想出一个原型 PowerShell 解决方案。不过，我可以分享我编写它的过程。

这将向您显示所有可以过滤的属性。我之所以提到这一步，是因为这里的信息与批处理文件中使用的信息略有不同。让我们看看MainWindowTitle。
MainWindowTitle : Administrator: Windows PowerShell
它包含确切地窗口标题栏中显示的内容。如果我们想根据此内容过滤选择，则可以使用以下命令：
> Get-Process | Where-Object -Filter-Object MainWindowTitle -Like "*PowerShell*"
这就是您确定该进程是否正在运行的方法。为了在条件语句中使用它，您可以执行以下操作：
> $process = Get-Process | Where-Object -Filter-Object MainWindowTitle -Like "*PowerShell*"
> $process.Count
1
> If ($process.Count -gt 0) { Write-Host Yes } Else { Write-Host No }
Yes
然后您可以使用 启动该应用程序Start-Process。
通过使用PowerShell，您的脚本将更加健壮，并且只有两行代码。
$process = Get-Process | Where-Object -Filter-Object MainWindowTitle -Like "Grain*"
If ($process.Count -eq 0) { Start-Process FTView.exe }
如果您使用Get-Help Start-Process，您将看到它有一堆可用于启动该过程的选项，例如传递参数、使用凭据、隐藏窗口等。
