Quoting jexec(8):

| DESCRIPTION                     
|     The jexec utility executes command inside the jail identified by its jid
|     or name.

The -n option is still there, but silently ignored.

Note, however, that the jail name jexec(8) is talking
about is not the same as the host name.

By default the jail id is used as jail name:

fk at r500 ~ $jls -n name jid
name=1 jid=1
name=2 jid=2
name=3 jid=3

So while jexec allows you to use the jail "name", it seems
to lack the "accept hostname or ip-number" feature mentioned
in the wiki, unless a non default jail name is used.
