i can thought that it will open a shell, execute the parameter (shell command) and return the result in a scalar. But, execute 'system' function in a perl script is faster than a shell command. It will call this command in C? If yes, what's the difference between

rmdir foo

and

system('rmdir foo');

Thanks,
