yes I also found a more direct way,
use Image::Resize;
$image = Image::Resize->new('large.jpg');
$gd = $image->resize(250, 250);
thanks for everyone.

Hi,
$ perl -le 'system "df -h"'

The both two styles work fine.
what's the difference between them and which is better usage?

The first spawns a shell and can handle things like globs. This is less
efficient, more powerful, and more dangerous (susceptible to code injection
attacks)
The second does not spawn a shell and therefore cannot handle globs. It is
also less susceptible to code injection attacks.

Thanks John and Chas.
I have got it.

Hi,
Hello,
what's the difference between these two calling for system() function?
system "command","-a","-b","-c";
system "command -a -b -c";
and, which is better?
They both do exactly the same thing.
