Environment path set to "PATH" variable missing after system restart?

Question

I have set

export PATH=$PATH:/home/user/android-sdk-linux/platform-tools

and execute the above line in command line and later if I type echo $PATH, I could see the path added. But after restarting the system I couldn't see it any more. But putting the system to sleep and then starting again, I could still see it. How to resolve the issue?

Answer 1

Adding it using export on command line would just set it for the current session.To set it permanently you need to add it to .bashrc or /etc/profile.
