Hi Jose,

As far as I know, the Windows cmd.exe environment doesn't let you
background a process the same way a unix shell does with '&'. However,
I have used "start" to achieve a similar effect when launching a script:

C:\> start /b perl script.pl

Type "start /?" at a cmd prompt to read about the "/B" switch. With
this switch, you'll still have the cmd.exe window open, but the prompt
will return immediately.

Also, I use this with Strawberry Perl; I don't know if ActiveState has
other tricks you can use.

Hi Jose,
If you are using ActiveState you could use wperl.exe from your CLI, instead
of perl.exe.

If you are trying to run this at Startup you can set up the AutoExnt service
to run a .bat that launches the .pl file.

@Timothy - Sorry for the reply.

From the GUI: open a new Command Prompt, start the program, minimize
the window until its done.

To do it from a Perl script, you'll need Win32::Process

It depends what you expect of a background program.

At a cmd prompt,

start perl script.pl

will start the program executing in a new window of its own, and all IO
to stdout and from stdin is done through that window. Another cmd prompt
will appear straight away in the original window unless you use

start /wait perl script.pl

Alternatively, as Brian says

start /b perl script.pl

starts the program without opening a new window. Anything it sends to
stdout will appear in your current current window, but there is no way
to type anything to stdin.

Finally, if by 'background' you mean to run the program at low priority,
then

start /low perl script.pl

is what you need.

Clearly these command qualifiers can be combined as necessary.

If you mean "running it without a console window", then Win32::Detached i=
s what you want to use.
