I'm assuming you're on Windows. Perhaps you don't have a "C:\temp"? (Be careful to either use "C:/temp" note the use of double quotes and the forward slash or to use 'C:\temp' single quote and backslash. If you double quote and backslash you'll have to escape the backslash i.e. "c:\\temp". Also: add a my to the $dir as in 
my $dir='c:\temp';
