Hi, I wrote multiple scripts in perl & shell and I had compared the real execution time. In all the cases - Perl script is more than 10 times faster than shell script. So i wondered if it possible to write a Shell script which is faster to the same script in perl? and why perl faster than shell although I use the 'system' function in perl script.

Thanks for your help, Regards, JohnJohnGa
