On Solaris, what is a terse way to get the fully qualified domain name (fqdn) for the current host

Question

When I want the fully qualified domain name on Linux, I can write ...

hostname --fqdn

To get the same thing on Solaris, is it necessary to write ...

cut -f 2-3 /etc/hosts | grep ^`hostname`\t | cut -f 2

... or is there something more brief?

From here:

The hostname command should return an FQDN...
...
The solution is to edit /etc/nodename and put the FQDN in there and reboot.
    echo foo.your.domain.com > /etc/nodename

You might also be able to use:

getent hosts `hostname` | cut -f 3

or similar.

Will "getent hosts | cut -f 3" depend on the layout of /etc/hosts ? – Thomas L Holaday Feb 01 '11 at 17:12
@Thomas: Yes. That command retrieves the same field as your command. You could try to use a `sed` or AWK command to be more flexible and selective. – Dennis Williamson Feb 01 '11 at 18:01

Your method depends upon the /etc/hosts file being formatted in a particular way, on a S10 system I have to hand it returns loghost which is incorrect.

If set up you can ask the DNS system with

dig -x your.ip.add.ress +short

or if you are using NIS then

echo `hostname`.`domainname`

or you could setup /etc/nodename as Dennis suggests.

Would two digs be better than one?

dig -x `dig +short "$(hostname)"` +short

Just be mindful of the trailing dot.
