`fish` also sends additional information to the user through the values of certain environment variables. The user cannot change the values of most of these variables.
- `_`, the name of the currently running command.
- `_`, the name of the currently running command (though this is deprecated, and the use of `status current-command` is preferred).
- `argv`, an array of arguments to the shell or function. `argv` is only defined when inside a function call, or if fish was invoked with a list of arguments, like `fish myscript.fish foo bar`. This variable can be changed by the user.
