Operating Systems OS X (Apple) .local hostname available as an environmental variable? Post 302555581 by gentinphilly on Thursday 15th of September 2011 06:30:41 AM

.local hostname available as an environmental variable?

Hola -

I've got a script for logon which populates a database with some info when a user logs on so that we can tell how many public terminals are in use & show users which ones are free. However, the machines are DHCPed and so using $HOSTNAME gives me an unstable name for them since of course the leases may change.

Is it possible to determine the .local hostname programatically and put it into an environmental variable I can call? We don't have too terribly many of these so that if I had to set an variable for each one by hand & call that I could do so, but of course, I'm hoping the .local name is available to me somehow.

Many thanks for any help or pointers here, greatly appreciated.

NAME
dhclient.leases - DHCP client lease database DESCRIPTION
The Internet Systems Consortium DHCP client keeps a persistent database of leases that it has acquired that are still valid. The database is a free-form ASCII file containing one valid declaration per lease. If more than one declaration appears for a given lease, the last one in the file is used. The file is written as a log, so this is not an unusual occurrence. The format of the lease declarations is described in dhclient.conf(5). FILES
