After adding the above line to the .bashrc file, the load

library path will be the same for every terminal and doesn't have to be set each time a new terminal is opened.

If you want this path to be available to any terminal that is

open you will have to "source .bashrc" at the command prompt. Otherwise, just close all active terminals and open new ones.

Errm don't you need to export that ie;
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:home/linux/lib
export LD_LIBRARY_PATH

No.  Not in the .bashrc file.

I tried this both it /etc/bashrc and ~/.bashrc, it doesn't work without exporting it.

It'll be working for linux user because in the example shown, the variable LD_LIBRARY_PATH will already be in the environment and hence already exported.
