echo $LD_LIBRARY_PATH

    If you want to run a script for the purpose of modifying environment variables you need to source the script rather than run the script. Running the script starts a new instance of w/e shell is used to run the script, when it returns, all environment variables are back to the way they were before you ran it. Doing “source script.sh” actually runs the commands in the script in your current shell.
