Re: LD_LIBRARY_PATH is not exported to subshells

[Randy Belk]

When you first login Bash will read /etc/bash.bashrc and also
$HOME/.bashrc to set stuff like your path($PATH) and other environment
variables. Always put your LD_LIBRARY_PATH exports in either of these
two files. New bash screen sessions will always read /etc/bash.bashrc
and also $HOME/.bashrc on startup! You don't need to write a script
use VI and add the   LD_LIBRARY_PATH to these file once and your done.
