You will have FAR fewer problems if you stop treating Perl like bash or
ksh (which are simply frameworks to execute system commands) and start
treating Perl like a programming language with its own system
interaction command set. Instead of shelling out to system calls to do
stuff like this, use Perl functions (such as readdir and unlink,
instead of 'ls' and 'rm').

Every time you execute a system command, you invoke a new shell
instance. Stop doing that, and your problems will (most likely) simply
go away.
