## Setting a variable from a file

> 📘 Setting variables from a file is a convenient way to set complex variables that contain spaces, newlines, or other special characters.

```shell theme={null}
# This will read file.txt and set it as VARIABLE

aptible config:set --app "$APP_HANDLE" \
        "VARIABLE=$(cat file.txt)"
```

> ❗️ Warning: When setting variables from a file using PowerShell, you need to use `Get-Content` with the `-Raw` option to preserve newlines.

```shell theme={null}
aptible config:set --app "$APP_HANDLE" \
        VARIABLE=$(Get-Content file.txt -Raw)
```

## Deleting variables

To delete a variable, set it to an empty value:

```shell theme={null}
aptible config:set --app "$APP_HANDLE" \
        VARIABLE=
```
