for Perl use rename()
for shell use the mv command

if you really want to use mv in Perl(I don't suggest this though)
Code:
`mv a b`;
or
system("mv a b");

make sure you check the return code.

There is no technical reason to use mv in a Perl script because the functionality is already built-in. Use the native function to avoid creating additional processes(fork).

Check the value of $?. See http://perldoc.perl.org/perlvar.html. for additional information.
