Get what syntax errors?

[edit] OK, I see some obvious ones. My line breaks weren't just ornamental, this:

Code:
while true do sleep 1 done

is not the same as
Code:
while true
do
        sleep 1
done

If you want to cram it on one line, use semicolons:
Code:
while true ; do sleep 1 ; done

You'll need to fix the other while loop as well, and that if-statement.

And please remove the "while true ; do sleep 1 ; done". Take a close look at what it does.

DESCRIPTION

       avahi-dnsconfd  connects  to  a	running  avahi-daemon  and  runs the script /etc/avahi/dnsconfd.action for each unicast DNS server that is
       announced on the local LAN. This is useful for configuring unicast DNS servers in a DHCP-like fashion with mDNS.

OPTIONS

       -D | --daemonize
	      Daemonize after startup and redirect log messages to syslog.

       -s | --syslog
	      Log to syslog instead of STDERR. Implied by --daemonize.

       -k | --kill
	      Kill an already running avahi-dnsconfd. (equivalent to sending a SIGTERM)

       -r | --refresh
	      Tell an already running avahi-dnsconfd to refresh the DNS server data. (equivalent to sending a SIGHUP)

       -c | --check
	      Return 0 as return code when avahi-dnsconfd is already running.

       -h | --help
	      Show help

       -v | --version
	      Show version information

FILES

       /etc/avahi/avahi-dnsconfd.action: the script to run when a DNS server is found or removed.

SIGNALS

       SIGINT, SIGTERM: avahi-dnsconfd will shutdown. This is issued by passing --kill to avahi-daemon.

       SIGHUP: avahi-dnsconfd will refresh the DNS server data.
