There's a question of env variables, when the child shell is killed
it does'nt pass on it's env variables to it's parent process unless,
exported . If all you want to do is go to a particular directory on login
put cd /usr/local in the .bash_profile.
If you want to go when you want put it in a script and run it in the present
shell with a $. <script name> ( not sh)
