system command in perl - prompt does not return back - window

[Selva123]

Hi All,
Greetings. May be simple issue but your help sought.
I am executing the system command like
$res=system("no tepad.exe"); thro a perl file named aa.pl.

At command prompt - when I enter
perl aa.pl , I could see that notepad was opened but the control - I say as prompt ( in windows) does not return back.
It looks like perl response is hanging.
I have to stop the precess with ctrl+c

Any idea ??

The system function will block until the executed command completes, which in this case is when you close/exit notepad.

Please read: `perldoc -f system` http://perldoc.perl.org/functions/system.html

If you want to create a detached process, you could use the Win32::Process module.

You can use the exec command to create a detached process.

exec("notepad.exe")
