Also, the .bash_profile is always sourced at the beginning of each shell
session, but I believe .bashrc is only sourced if your shell is explicitly
told to at some point (either by some global profile script or your
.bash_profile itself). If you believe that your .bashrc is not being
sourced when you launch a new shell, add the following 3 lines to your
.bash_profile
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
This will source your .bashrc in your home directory only if it exists, and
it will do so each time your start a new shell. I typically find this good
practice rather than editing your .bash_profile since .___rc files are
pretty universal across many different programs, and it prevents the
.bash_profile from getting too cluttered. Lastly, you have to export
AMBERHOME before you use it to expand your PATH variable. Again, 'set' is
only used for csh to set environment variables, so use export only.
