Quoting jexec(8):

| DESCRIPTION                    =20
|     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@r500 ~ $jls -n name jid
name=3D1 jid=3D1
name=3D2 jid=3D2
name=3D3 jid=3D3

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.
