Launch windows exe from perl

[Troot]

Hi,

Im trying to launch an application (exe) from perl once I've processed
a file, but I can't find the correct command. Could somebody point in
the right direction?

Appreciated
Troot

ps Do you know if there is a way to get Perl to wait until the opened
app is finished? Its cool if its too difficult to do.

The command you're looking for is 'system'. Read about it in:
perldoc -f system

ps Do you know if there is a way to get Perl to wait until the opened

That is, in fact, the default behavior of system. If you wanted it to
not wait, you'd have to do some magic involving fork()...

1) Please quote some context when replying to a Usenet group - not
everyone reads Usenet via a threaded interface.

2) When you're looking for a function, and you don't know its name, a
good place to start is:
perldoc perlfunc
which contains a list of all of Perl's functions, organized by
category.

Hope this helps,

If you're using Win32, there's no need to use fork(). You can just
use the "start" command inside the call to system(), like this:

system("start notepad.exe");

This will start the "notepad.exe" application without halting the Perl
script.

Huh, good to know. I rarely program in Windows, so I'd never
encountered that. Thanks for the tip.

Another one, if you want to open the current directory in a cmd.exe use:

start .
