# Run command with a single environment variable configured

```console
$ <KEY>=<VALUE> <command ...>
```

# Run command with multiple environment variables configured

```console
$ env <KEY1>=<VALUE1> <KEY2>=<VALUE2> [<KEY3>=<VALUE3> [...]] <command ...>
```

Works in Linux, BSD, MINIX, ...

That should save some setup scripts and polluting the shell session with (potentially sensitive) exported variables!
