When you run a script in a subshell, it can modify the environment of
that subshell, then that subshell terminates (when the script is done)
and you get the prompt from your original shell again. Unlike MS-DOS,
scripts normally run in subshells and can't wreak havoc on your
environment. If you want to run the script in the current shell, use
one of the following commands :
. ./.bash_profile
source ./.bash_profile
