使批处理文件等待，直到执行由Perl脚本（由批处理文件调用）的shutdown命令

Question

I have a batch file which calls a Perl script and then the Perl script which does some processing and then executes a command shutdown /r /t 1 . In the batch file after the Perl is called, there is exit /b . For instance:

Batch file:

perl doSomething.pl

exit /b

Perl file:

do stuff

shutdown /r /t 1

I want the batch file to not exit and wait until the shutdown begins.

I have tried

start /wait perl dosomething.pl

and looping with tasklist to check for perl.exe and exit only if perl.exe process has finished. Nothing worked.

Is there a solution to achieve this without 'sleeping' or infinite loop wait until shutdown?

Answer 1

Well, that's strange. It simply HAS to work with the last option, you've mentioned (checking the task list).

However, the only option I can think of is to create a kind of flag file. Let your perl script create a file somewhere just before it terminates and make your bat loop around until this file is found and delete it before terminating. To avoid "busy waiting" you could add something like ping localhost -n 6 >nul inside your bat loop.
