 ## Examples
 
 ### I want to have 2 replicas of first_dataset and second_dataset on Tier 1 RSEs
 
-The number 2 *second_dataset* is the number of copies expected. At the end, the
-RSE Expression select all the Tier 1 RSEs as possible targets to store the
-replicas.:
-
 ```bash
-username@host:~$ rucio add-rule scope:first_dataset scope:second_dataset 2 'tier=1'
+username@host:~$ rucio rule add --copies 2 --rses 'tier=1' scope:first_dataset scope:second_dataset
 ```
 
-To see all the possible targets, **rucio list-rses** command can be used:
+To see all possible targets, the command `rucio list-rses` can be uses with the same RSE expression:
 
 ```bash
-username@host:~$ rucio list-rses --rses 'tier=1'
+username@host:~$ rucio rse list --rses 'tier=1'
 ```
 
 ### I want to have 2 replicas on whatever T2 RSEs in the UK but not in Glasgow
 
 ```bash
-username@host:~$ rucio add-rule scope:first_dataset scope:second_dataset 2 'tier=2&country=uk\site=GLASGOW'
+username@host:~$ rucio rule add --copies 2 --rses 'tier=2&country=uk\site=GLASGOW' scope:first_dataset scope:second_dataset
