Need help with creating a script for Snmpwalking
Hello,

Very new to scripting, basically learning on the job. So, I have a task I'm trying to complete. What I need is comparing an input file and running the snmpwalk command to find out which 3 community strings a device is using.

this is what I have so far:

(I've replaced what the community string is with just community01/02/03)

Code:
while read line
do
                device_ip=`echo $line | cut -f1 -d","`
                
		device_name=`echo $line | cut -f2 -d","`
		
		alarm_title=`echo $line | cut -f3 -d","`


if [[ $alarm_title == "MANAGEMENT AGENT LOST" ]]; then
		snmpwalk01=`snmpwalk -v 2c -c community01 "$device_ip" sysName.0`
		
		if [[ -z "$snmpwalk01" ]; then
			snmpwalk02=`snmpwalk -v 2c -c community02 "$device_ip" sysName.0`

			if [[ -z "$snmpwalk02" ]]; then
				snmpwalk03=`snmpwalk -v 2c -c community03 "$device_ip" sysName.0`
				
				if [[ -z "$snmpwalk03" ]]; then
					echo "$device_name"="unknown"
				fi					
			fi

		fi
fi

I'm sure I've completely butchered everything...but this is what I've got by googling, looking at scripts already on the server, etc etc.

Like I said, I have an input file that has the Device IP, Device Name, and the Alarm Detail. Not all of the alarm details are "Management Agent Lost". What I'm trying to do is take one line from that input file, see if the community01 works as a community string. If it doesn't, then test community02. If that doesn't work, test 03.

If none work, echo the device name and the result.
If one of them works, echo device name and the community string that does work.

uudemon

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
