How do I make an environment variable permanent in Linux?

You can make an environment variable permanent by adding it to your shell's configuration file, like ~/.bashrc or ~/.bash_profile.

Can you show me an example of how to do that?

Sure! To add a variable, open your ~/.bashrc file with a text editor and add a line like 'export MY_VAR=value'. Then, run 'source ~/.bashrc' to apply the changes.

What if I'm using a different shell, like zsh?

If you're using zsh, you would add the export line to your ~/.zshrc file instead and then run 'source ~/.zshrc'.

Is there a way to check if the variable is set correctly?

Yes! You can check if the variable is set by running 'echo $MY_VAR' in the terminal.
