An example of an AI chatbot conversation about environment variables in various shell environments.
How do environment variables work in different shell environments?
Environment variables are key-value pairs used to configure the behavior of processes in different shell environments like Bash, Zsh, and Fish.
Can you give me examples of how to set an environment variable in Bash and Zsh?
In Bash, you can set an environment variable using export VAR_NAME=value. In Zsh, it's similar: export VAR_NAME=value.
Are there any differences in how these shells handle environment variables?
Yes, while the syntax is similar, Zsh has additional features like automatic export of variables when defined.
What about Fish shell? How does it differ?
In Fish shell, you set an environment variable using set -x VAR_NAME value, which automatically exports it.
