The Perl command opens a new instance of the shell, not the one you called Perl from. The new instance has no history to report.

Not until you learn a little more about Unix shells. Your command worked perfectly, it just didn't output what you expected. The history command in bash returnes the command history of the current shell. Since you just opened it via the system call, it has no history, so it returns an empty string. That behavior is correct. Now, what are you actually looking for?
