Commands for Setting Environment Variables
You can create environment variables to control the behavior of a command. Apple’s support page states that this does not modify the command itself. Apple gives an example of using an environmental variable to set up a command print debug. Apple states, “To set the value of an environment variable, use the appropriate shell command to associate a variable name with a value.” For example, Apple gives the following command to set the variable PATH to a value: Here, the value would be Adding “% PATH=” before the value and “export PATH” after the value sets the variable PATH. According to Apple, this command can help you view all environmental variables: Variables set in any individual Terminal window are not available after you close that window. If you want to keep the variable, you have to set up a shell startup script. You can find information for how to do this on the zsh man page under Invocation. The Apple support page has a link at the bottom of the page that opens the man page in your Terminal. The above article may contain affiliate links which help support Guiding Tech.
