This topic is getting far more complicated than you might expect. Setting
environment variables needs to be done from your .bash_profile . It
happens once when you log in and all child processes inherit the resulting
variables.
If you use su then you do not go through the .bash_profile unless you use
the - option. i.e., "su - bob" will go through bob's .bash_profile but
"su bob" will only go through the .bashrc .
The same is true of ssh. If you ssh to a host to create a session then you
will go through the .bash_profile but if you ssh to a host to just execute
a command then you will only go through the .bashrc .
The proper way to deal with this is to:
* Source in your .bashrc from your .bash_profile
* Set all of your environment variables in your .bash_profile
* Check in your .bashrc to see if PS1 is set. If not then you are not in
an interactive session and you need to set critical environment variables.
Usually PATH is the only one you need to set.
if [[ -n "${PS1}" ]]
then
: Do interactive stuff. Set aliases and variables, etc.
else
. ~/.bash_pathset
