Takes a string containing the name of the variable as input. Returns
|
|
an empty string if the variable is not set, otherwise returns the
|
|
value of the variable.
|
|
|
|
```
|
|
{{ getenv "HOME" }}
|
|
```

In Unix-like environments, the variable must also be exported in order to be seen by `hugo`.
