Executing below two commands on mac Terminal which set environment variable, which is vanished on close of Terminal, any help would be appreciated 

Step 1:- echo "export JAVA_HOME=`/usr/libexec/java_home`" >> ~/.profile 
Step 2:- . ~/.profile

Initial Terminal output 

karthiks-MacBook-Air:~ karthicklove$ echo "export JAVA_HOME=`/usr/libexec/java_home`" >> ~/.profile

karthiks-MacBook-Air:~ karthicklove$ . ~/.profile

karthiks-MacBook-Air:~ karthicklove$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home

Terminal output after closing and reopen again

karthiks-MacBook-Air:~ karthicklove$ echo $JAVA_HOME

karthiks-MacBook-Air:~ karthicklove$

Create a file called .bash_profile in your home directory and add the JAVA_HOME variable in it.

export JAVA_HOME=`/usr/libexec/java_home`

This file is loaded every time you open terminal or you open a new terminal tab. Please note that the file needs to be hidden.
