Display current environment variables
fxdeMacBook-Pro:~ fx$ printenv
The above command shows all environment variables if you want to view an environment variable:
fxdeMacBook-Pro:~ fx$ echo *** (the name of the environment variable you want to view)
Change environment variables once:
export [existing_variable_name]=[new_value]:$[existing_variable_name]
Permanently set environment variables:
Add to the .bash_profile file, vi ~/.bash_profile, if the file does not exist, the command will create the file
Export environment variable name=value
Restart the command line to load the new environment variables.
