Any such script is going to be very environment specific - so you might get more advice if you actually mentioned your environment. Windows? Linux? Solaris?

Normally you cannot hide processes under Unix, or Windows without using some form of rootkit.

Hiding windows should be trivial though - for example this console program allows you to hide windows under Windows, but this isn't perl and your question has nothing to do with perl at all.
