Double echo problem
I'm parsing a router configuration file and printing out some of the fields. Given the following output,
I'd like to add the filename to the first column. I'm definately a neophyte in scripting.


COUNTER=${#array1[*]}

while [ $COUNTER -ne -1 ]; do
######## echo -n $JUNOS_FILE | awk '{ printf "%-20s" , $0 }'
echo ${array0[$COUNTER]} | awk '{ printf "%-20s" , $1 }'
echo ${array3[$COUNTER]} | awk '{ printf "%-50s" , $0 }'
echo ${array2[$COUNTER]} | awk '{ printf "%-20s \n" , $1 }'
let COUNTER=COUNTER-1
done

------------------------- OUTPUT ---------------------------------------------------------------

lo0 LB rtr-management 127.0.0.1/32
t1-1/0/1 TZ Unused
t1-1/0/0 S3/0/16:0 ATT 69DHZA382XXX 10.255.74.62/30
ge-0/0/3 GE Reserved for WAN
ge-0/0/2 GE ZZZ-Test 10.213.0.109/30
ge-0/0/1 GE Unused-ge-0/0/1
ge-0/0/0 GE ECD_28307_00 Juniper J2320 10.213.101.19/27

When I try to add the filename the I get an extra row on top that I don't want. Appears to be
the filename echos twice somehow.

Any ideas??

NAME

       rdpd - router discovery protocol daemon (OBSOLETE)

SYNOPSIS

       | |

DESCRIPTION

       the router discover protocol daemon, implements the host portion of the router discovery protocol (see More specifically

	      o  solicits router advertisements when it is first started so as to populate the kernel table as soon as possible.

	      o  listens on all ethernet interfaces (that are up) for ICMP router advertisement datagrams.

	      o  adds  a  default  router  to  the kernel table based on whether the router is a neighbor and has the highest preference among all
		 advertisements received.

	      o  ages the default router entry applied to the kernel table based on the lifetime value found in the advertisement message.

       can be started during boot-time initialization.	To do so, see (But see below.)

   Options
       supports the following options:

	      Display the version of

	      Enable tracing of the following events:

			o  setting of expiration timer for advertised entry.
			o  expiration of a router advertisement entry (only the active entry has a timer running).
			o  add/update of an advertised router to the kernel.
			o  removal from kernel table of an advertised router.
			o  reception of a router advertisement from the link.
			o  transmission of a router solicitation message.
			o  failure while attempting to transmit a solicitation.

	      Enable verbose tracing, which in addition to the above, traces:

			o  contents of the router advertisement message received.
			o  contents of rdpd internal statics which includes:
				1.  total number of messages received,
				2.  total number advertisements received,
				3.  total number of advertisements with invalid number of addresses field,
				4.  total number of advertisements with invalid address size field,
				5.  total number of advertisements with invalid message lengths,
				6.  total number of advertisements with invalid lifetime fields,
				7.  total number of messages with number of bytes received <> header length field.

LIMITATIONS

       1. The maximum number of default routes retained is 10.	Only one of which is applied to the kernel routing tables (the one with the  high-
	  est  preference).   In the event that the advertised router with the highest preference expires the retained advertised router list will
	  be searched for the highest preference, still current entry and that entry will be applied to the kernel table.  This allows	for  quick
	  recovery from aged advertisements.

       2. only	becomes  aware of link state changes when either a new Router Advertisement message is received or a timer pops to age a currently
	  active default router added by This may cause a delay between an interface state change (e.g., down) and any	necessary  change  to  the
	  kernel routing table.

       3. The  "all  hosts  on subnet" broadcast address is used for sending solicitations instead of either the all-routers multicast or limited-
	  broadcast IP addresses.

       4. The limited-broadcast address for inbound Advertisements is assumed.

       5. Default routers added via the command can be altered due to Router Advertisements for the same router.

       6. Adding default routes via the command can cause unpredictable results and should be avoided.
