I don't know if it is better to discuss it in jail@ or stable@ list so a 
do cross-post.

FreeBSD has many jail aware utilities but they are inconsistent in 
taking JID as parameter.

For example "sockstat" takes -j JID "Show only sockets belonging to the 
specified jail ID" and it means numeric ID only.
On the other hand "ps" takes -J JID "This may be either the jid or name 
of the jail.  Use -J 0 to display only host processes."
The same apply for "top", it understands jid as a number or name of the 
jail too.
Then again "cpuset" takes only numerical ID of the jail...

Shouldn't it be consistent across all FreeBSD base utilities so all of 
them can use numerical ID and name?

Should I file a PR for it?

PS: I am on FreeBSD 10.4 so I don't know if something is different in 
newer branches
