[ic] how to run system command in [perl] tag

[Shailesh Setha]

Hello All,

I am trying to create downloadable items.
For that I want to use 'system()' command.
I have written like this

[perl]
$dir="xyz";
system("mkdir $dir"); # (and this also system('mkdir $dir');)
$out="The directory $dir is created.";
return $out;
[/perl]

But no effect, no directory is created and nothing is returned.
I have changed the owner to root.
Does Interchange allow system commands?
If not is there any other way to do so?
Or can I change the some variable to enable this command?

Any help is greatly appreciated.
Thanks in advanced.
