write a shell script to execute a command

Hello all,
I have just started doing shell scripting.
I want to read a file which stores the status of my job I have submitted
on a cluster.
The file looks something like this :
========================FILE=============================

crab: Checking the status of all jobs: please wait
crab:
ID STATUS E_HOST EXE_EXIT_CODE JOB_EXIT_STATUS
--------------------------------------------------------------------------------------------
1 Done
2 Done

crab: 2 Total Jobs
=====================================================

The highlighted lines display the status of the jobs. The status shown is done. Whenever it is done I want to give a command which is "getoutput" to retrieve my jobs.
So I want to write a small script which can read this file and whenever it is
done it just retrieves the output.
Could somebody tell me if there is a way to do this using shell script?

This is something which I tried doing but didnt work. "out" is file which stores the output info

==================================line========================================

flag[1]=0
flag[2]=0
cat out | gawk 'BEGIN{i=1;}{if($2=="Done") { $flag[i]=1; }'

if($flag[1]==1 && $flag[2]==1); then
getoutput
fi
================================================================================

But this doesnt seem to work because it seems that its treating flag[1] & flag[2] as local variables inside
gawk.


Thanks

queuedefs(4)							   File Formats 						      queuedefs(4)

NAME
queuedefs - queue description file for at, batch, and cron SYNOPSIS
/etc/cron.d/queuedefs DESCRIPTION
The queuedefs file describes the characteristics of the queues managed by cron(1M). Each non-comment line in this file describes one queue. The format of the lines are as follows: q.[njobj][nicen][nwaitw] The fields in this line are: q The name of the queue. a is the default queue for jobs started by at(1); b is the default queue for jobs started by batch (see at(1)); c is the default queue for jobs run from a crontab(1) file. njob The maximum number of jobs that can be run simultaneously in that queue; if more than njob jobs are ready to run, only the first njob jobs will be run, and the others will be run as jobs that are currently running terminate. The default value is 100. nice The nice(1) value to give to all jobs in that queue that are not run with a user ID of super-user. The default value is 2. nwait The number of seconds to wait before rescheduling a job that was deferred because more than njob jobs were running in that job's queue, or because the system-wide limit of jobs executing has been reached. The default value is 60. Lines beginning with # are comments, and are ignored. EXAMPLES
Example 1: A sample file. # # a.4j1n b.2j2n90w This file specifies that the a queue, for at jobs, can have up to 4 jobs running simultaneously; those jobs will be run with a nice value of 1. As no nwait value was given, if a job cannot be run because too many other jobs are running cron will wait 60 seconds before trying again to run it. The b queue, for batch(1) jobs, can have up to 2 jobs running simultaneously; those jobs will be run with a nice(1) value of 2. If a job cannot be run because too many other jobs are running, cron(1M) will wait 90 seconds before trying again to run it. All other queues can have up to 100 jobs running simultaneously; they will be run with a nice value of 2, and if a job cannot be run because too many other jobs are running cron will wait 60 seconds before trying again to run it.
