The script runs in a subshell.  Thus everything you do affects the
subshell (which terminates when the script is finished) and you return
to the same old shell you had before.  Use a function in your .bashrc
instead, or "source" the script (no need for the shebang then).

(notice : this is the inverse of .bat files)
