Hey there dear people! :slightly_smiling_face: very quick question, I defined an evironment variable in my BUILD file for my package this way:

```pex_binary(
    name="bin",
    entry_point="main.py",
    env={"VAR_NAME": "var_value"},
)```
Is it possible to pass this (or override this) at runtime when I run `pants package path/to/package:bin`  instead of defining it in the BUILD? Thanks so much! :pray:

Something like `pants package --env VAR_NAME=my_new_var_value path/to/package:bin`  ? tried to look for it but it doesn't seem to exist

Yes <https://www.pantsbuild.org/docs/targets#environment-variables> :slightly_smiling_face:

Example:
```pex_binary(
    name="bin",
    entry_point="main.py",
    env={"VAR_NAME": env("VAR_NAME", "var_value")},
)```
if you want to keep what you have now, but add the possibility to override from the command line `VAR_NAME=new_value pants package path/to:bin`

Works like a charm! always a life saver thanks so much dear <@U01PZK60W2F>! :pray:
