With the BSD (and macOS) `md5` command, the `-q` option is not really "silencing", but it prints out only the checksum in that case:

```
     -q      Quiet mode - only the checksum is printed out.  Overrides the -r option.
```

GNU coreutils `md5sum` does not have an equivalent option: you must always parse the standard output, and take the first printed field as the checksum.

Note that GNU `md5sum` indeed has a `--quiet` option, but its meaning is rather different: it can only be used in `--check` mode, and then its effect is that it does not show `OK` for each correctly verified input file.
