|
|
The .nu-env file has the same format as your $HOME/nu/config.toml file. By loading a .nu-env file the following applies:
|
|
- environment variables (section \"[env]\") are loaded from the .nu-env file. Those env variables only exist in this directory (and children directories)
|
|
- the \"startup\" commands are run when entering the directory
|
|
- the \"on_exit\" commands are run when leaving the directory
