Each zone file (something like /etc/named/pri.domain.com) has a line
similar to this:

$TTL 36000

(but with a different number)

Create a shell script to edit these lines and change them to:

$TTL 60

for each file (I leave how up to you, Avi).

Then restart the nameserver, but NOT through the GUI.

# kill -HUP `cat /var/run/named.pid`

(note the back-ticks)

WARNING: Don't do anything DNS-related  through the gui until you want
to change them back.

To change everything back, just do something DNS-related, and click on
SAVE CHANGES.
