What is .bashrc

What is .bashrc ?

.bashrc contains the scripts that are executed when ‘BASH’ shell ( Bourne Again Shell ) is launched.  It basically contains the settings that must be enabled for a bash shell when it is launched. The ‘.bashrc’ exist at two levels ie one at the root level ( global one ) and another one at the user level ( ie shell settings specific for that particular user )

Global bashrc location : /etc/

User Specifc location : /home/username/

Ideally all your environment variables like JAVA_HOME should be set inside your .bashrc.

eg :

#Setting Java Home and Path Variable
export JAVA_HOME=/home/mindtree/java/jdk1.6.0_22
export PATH=$JAVA_HOME/bin:$PATH
export ODE_HOME=/home/mindtree/apache-ode-jbi-2.0-beta2
export RAPIDAPPSERVER_HOME=/home/mindtree/RCSBuildXMLFiles

Once you change the contents of .bashrc.  You need to execute the command

$source .bashrc

so that the changes take effect. If this doesn’t work, try starting a new terminal or a new tab within the existing terminal.
