Description

I commonly find myself needing to loop over all non-global zones to perform some sort of operation, e.g.

for z in `zoneadm list | grep -v '^global$'`; do
  something
done

As a convenience, it might be nice to have a list option that would elide the global zone entry. It looks like '-n' is available and would make sense. It should also combine with the -c/-i options to filter on state, so:

zoneadm list -n -c

would list all non-global zones in the configured state. Likewise for '-n -i' to show non-global, installed zones.

I've run the following tests to verify the code.

ryan@openindiana:/code/illumos-gate/proto/root_i386/usr/sbin$ ./zoneadm list -in
example

ryan@openindiana:/code/illumos-gate/proto/root_i386/usr/sbin$ ./zoneadm list -cn
example

ryan@openindiana:/code/illumos-gate/proto/root_i386/usr/sbin$ ./zoneadm list -zn
-zn: illegal option -- z
usage:  list [-cinpv]
        Lists the current zones, or a specific zone if indicated.  By default,
        all running zones are listed, though this can be expanded to all
        installed zones with the -i option or all configured zones with the
        -c option.  When used with the general -z <zone> and/or -u <uuid-match>
        options, lists only the specified matching zone, but lists it
        regardless of its state, and the -i, -c, and -n options are disallowed.  The
        -v option can be used to display verbose information: zone name, id,
        current state, root directory and options.  The -p option can be used
        to request machine-parsable output.  The -v and -p options are mutually
        exclusive.  If neither -v nor -p is used, just the zone name is listed.

One more example listed below.

ryan@openindiana:/code/illumos-gate$ proto/root_i386/usr/sbin/zoneadm -z example list -n
-n: illegal option -- n
usage:    list [-cinpv]
    Lists the current zones, or a specific zone if indicated.  By default,
    all running zones are listed, though this can be expanded to all
    installed zones with the -i option or all configured zones with the
    -c option.  When used with the general -z <zone> and/or -u <uuid-match>
    options, lists only the specified matching zone, but lists it
    regardless of its state, and the -i, -c, and -n options are disallowed.  The
    -v option can be used to display verbose information: zone name, id,
    current state, root directory and options.  The -p option can be used
    to request machine-parsable output.  The -v and -p options are mutually
    exclusive.  If neither -v nor -p is used, just the zone name is listed.
