## Example

Let's say you have a file `temp` with the following content:

```

${BAR}

${FOO:-foo}

```

When you run `BAR=baz npx --ignore-existing @inventage/envsubst temp`, you will end up with the following content in `temp`:

```

baz

foo

```

and the following output:

```

Made 2 replacements:

┌──────┬─────────────┬───────┐

│ File │ Variable    │ Value │

├──────┼─────────────┼───────┤

│ temp │ ${BAR}      │ baz   │

├──────┼─────────────┼───────┤

│ temp │ ${FOO:-foo} │ foo   │

└──────┴─────────────┴───────┘

```
