.zipix bash shell

./zipix is a simple bash script defined at the bottom of this description. barnyard's cygwin setup means that newly open cygwin shells, such as the one depicted in this fotograph, will be
immediately pointed to barnyard's "My Pictures" directory.. in the depicted shell, i have made it to "My Documents"
