Thanks for this sample, but it exceeds my script coding ability.
I added some comments to your sample but I may be lost.
#!/bin/sh
updater_prog = /usr/local/bin/noip2 # program to run
if [ x$reason = xREBOOT ] || \ # is this an reboot or
[ x$old_ip_address = x ] || \ # old ip field empty or
[ x$old_ip_address != x$new_ip_address ]; then # old not EQ
new then
if [ -x $updater_prog ]; then # don't know what
this does
${updater_prog} -i "$new_ip_address" # exec program
fi
fi
For my purposes I think this is what I need.
This way zoneedit is only updated when ip changes.
Do I have script correct?
/etc/dhclient-exit-hooks.sh with this content
#!/bin/sh
# This script only gets called when dhclient runs
# (IE: boot and lease expire)
# Old and new ip address fields are populated by dhclient,
# which keeps the old used IP address in some config file
# so it's not lost on reboot and can be read in at boot time to
# determine if the ip has changed. So with cable or dsl modem
# that stays powered on while PC is powered off still is
# using old IP address.
updater_prog = /usr/local/bin/wget....rest of command # my wget
pgm
if [ x$old_ip_address != x$new_ip_address ]; # old not EQ new
then ${updater_prog} # exec my pgm
fi

Yes.
As another example, my own script for a similar purpose:
