- Encode a file to `stdout`:

`base64 {{-i|--input}} {{path/to/file}}`

- Encode a file to the specified output file:

`base64 {{-i|--input}} {{path/to/input_file}} {{-o|--output}} {{path/to/output_file}}`

- Wrap encoded output at a specific width (`0` disables wrapping):

`base64 {{-b|--break}} {{0|76|...}} {{path/to/file}}`

- Decode a file to `stdout`:

`base64 {{-d|--decode}} {{-i|--input}} {{path/to/file}}`

- Encode from `stdin` to `stdout`:

`{{command}} | base64`

- Decode from `stdin` to `stdout`:

`{{command}} | base64 {{-d|--decode}}`
