I installed java-8 using a PPA. After that I gave a command:
I had heard somewhere that this command does temporary changes. But after many logouts and logins, these commands below still works (I think due to that
export ... command):
java -version javac -version
But when I give the command:
It shows a list of environment variables, but in that list, does not show variable
JAVA_HOME. Moreover, I wonder how the commands
javac still works!
Can someone tell me in which file
export command make changes? Are they temporary or permanent? And what else happens above? Please elaborate!
