I’m running RHEL6, and I’ve exported the following environment variable:
When the terminal is closed, that variable is gone. How can I make this a permanent addition so that this variable value is always associated with a specific user?

You can include it in your shell configuration file, such as $HOME/.bashrc, or in /etc/environment more broadly. On GUI-based systems, the changes won’t show up right away; you’ll need to close the terminal or establish a new one, and in servers, you’ll need to log out and back in to see the changes.

To set a permanent environment variable, you must change three files as follows:
In most cases, you’ll need to restart your computer to see these changes take effect. These commands, however, can be used to make changes to bashrc and profile:
$ source ~/.bashrc $ source ~/.profile
However, you have no choice except to restart /etc/environment (as far as I know)
To complete all of these tasks, I’ve built a simple script. All you have to do now is give your environment variable a name and a value.
#!/bin/bash echo "Enter variable name: " read variable_name echo "Enter variable value: " read variable_value echo "adding " $variable_name " to environment variables: " $variable_value echo "export "$variable_name"="$variable_value>>~/.bashrc echo $variable_name"="$variable_value>>~/.profile echo $variable_name"="$variable_value>>/etc/environment source ~/.bashrc source ~/.profile echo "do you want to restart your computer to apply changes in /etc/environment file? yes(y)no(n)" read restart case $restart in y) sudo shutdown -r 0;; n) echo "don't forget to restart your computer manually";; esac exit
Simply save these lines in a shfile, make it executable, then execute it!

Add the line to your.profile or.bashrc file. The settings in $HOME/.profile are only active for the current user; the variables in /etc/profile are global. Each time a bash session starts, the.bashrc file is loaded.
