in reply to system() does not wait for terminal.exe to complete executing on Windows

There is something wrong with the logic of your script. The wait is useless here and entirely unnecessary.

As coded, system should not return until the program started completes. I cannot think of any circumstance where that would not be the case.

For example, if you run this: 

perl -le"$|++; for( 1, 2){ print system qq[C:/windows/system32/notepad
+.exe];     print'hi'}"

You will see that you have to close notepad.exe before control returns to the perl script. It then prints 'hi' and the return value from the command. You have to close notepad twice before the above script completes.

    Thanks. Your code snippet helped me :-). Here is what I observed:- I was trying to run a short-cut(to an terminal.exe) with command line parameter in my original code. When I tried your code it behaved the same way. So I tried running the terminal.exe from its install location, and it worked :-). The script executes terminal.exe, waits for it to exit and then runs it second time. Thanks !!!

      Ah! Yes, shortcuts effectively detach their targets and then return. Which explains the behaviour you got.
