What is the Solaris equivalent of the Linux hostname -f command? On Solaris, when I type hostname, I receive the short name but I need to get the FQDN.

Typing hostname -f sets the short name to be "-f", and the manpage for hostname is pitiful.

/etc/nodename just lists shortname for the server. The /etc/hostname.* files are all giving me an error when I try to cat them :( – Matthew Nov 18 '11 at 18:48
What errors do you get with /etc/hostname.if? If those are corrupted then you have bigger problems. – James O'Gorman Dec 6 '11 at 20:27

This is likely to work:

perl -mNet::Domain -e 'print Net::Domain::hostfqdn(), "\n"'

but it's not guaranteed. You can view the module source:

perldoc -m Net::Domain

to see how it works (if you know Perl well enough).

If you are on a system that the DNS knows about, you could try this:

bash-3.00# nslookup `hostname` | grep 'Name:' | awk '{print $2}'

or, as suggested by a commenter, use "host" instead of nslookup:

host $(hostname) | cut -d" " -f1

I tested this successfully on Linux, Solaris, AIX, and HP-UX.

nslookup has been deprecated for a long time. host or dig are preferred and would involve fewer pipes: host $(hostname) | cut -d" " -f1 – James O'Gorman Dec 6 '11 at 20:26
@JamesO'Gorman nslookup is part of the POSIX standard, only a hairbrain OS wouldn't include it these days. – Chris S Mar 20 '13 at 4:04
@ChrisS True, and nslookup generally still comes with host and dig in the BIND utilities package (OS/distro dependent) but the output from dig is BIND zonefile-compatible and host is slightly easier to parse, therefore I'd say it's better to use host or dig if you can. – James O'Gorman Mar 21 '13 at 9:03
check-hostname | awk '{ print $NF }'
