In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
```go
annotations := make([]string, 3)
annotations[0] = "json"
annotations[1] = "yaml"
annotations[2] = "yml"
annotations := []string{"json", "yaml", "yml"}
annotation := make(map[string][]string)
annotation[cobra.BashCompFilenameExt] = annotations
flag := &pflag.Flag{"filename", "f", usage, value, value.String(), false, annotation}
flag := &pflag.Flag{
Name: "filename",
Shorthand: "f",
Usage: usage,
Value: value,
DefValue: value.String(),
Annotations: annotation,
}
cmd.Flags().AddFlag(flag)
```
