Inside a batch file, how can I tell whether a process is running?
提问by JosephStyons
I'd like to write a batch file that checks to see if a process is running, and takes one action if it is, and another action if it isn't.
我想编写一个批处理文件来检查进程是否正在运行,如果是,则执行一个操作,如果不是,则执行另一个操作。
I know I can use tasklist to list all running processes, but is there a simpler way to directly check on a specific process?
我知道我可以使用 tasklist 列出所有正在运行的进程,但是有没有更简单的方法来直接检查特定进程?
It seems like this should work, but it doesn't:

tasklist /fi "imagename eq firefox.exe" /hn | MyTask
IF %MyTask%=="" GOTO DO_NOTHING
'do something here
:DO_NOTHING

You can use "for /f" construct to analyze program output.
您可以使用“for /f”构造来分析程序输出。
set running=0
for /f "usebackq" %%T in (`tasklist /nh /fi "imagename eq firefox.exe"`) do set running=1
Also, it's a good idea to stick a
此外,坚持一个好主意
setlocal EnableExtensions
at the begginning of your script, just in case if the user has it disabled by default.
