 ( How to find out (list) the UUID and LABEL all the partitions? )

Para listar o código UUID (universally unique identifier) e LABEL (rótulo/nome) de todas as partições de todos os discos do computador com um único comando basta utilizar, como root, o comando blkid:

**sudo blkid**

Olhe a saída no meu computador:

**zumm@destino:~$ sudo blkid**
