What files are amended when you do a EXPORT?
 

Eg. EXPORT PATH=$PATH:/usr/local/bin

To which files is the above line "PATH=$PATH:/usr/local/bin" added to?

Thanks !

I don't think it does change any files.

If you want to set up environment variables that are retained after a reboot, you should add them to your bash profile (edit /etc/profile as root to change for all users - you can also create a profile for each user).

Hope this helps,

It's also typically a lowercase "export"
