Hi

I have created a shell script which uses three nested loops. When the cronjob is running the script there is a for loop which call a function which has two nested for loops. It is going into the function but the for loop in the function is not running. Can someone pleasae give me a solution for this. I have tried and removed the function also. Even with this the second for loop is not running.

You can find the shell script below:

#!/bin/ksh
#--------------- Make a file Broker.dat with all the Broker Names -----------
mqsilist |grep Broker |awk '{print substr($3,0,8)}' > /amp/home/mqsi/scripts/Broker.dat

function check_msg_flow {
BRKNAME=$1

for exec in `mqsilist $BRKNAME |awk '{print substr($4,0,8)}' |grep -v "completi"`
do
execgr=`expr $execgr + 1`
#------------ Check whether the execution group is in debug mode ------------

temp=`mqsireporttrace $BRKNAME -u -e $exec |grep -v "BIP8071I:" |awk '{print substr($4,0,5)}'`
if [[ $temp = debug ]]; then
printf "%-45s %-25s %-20s\n" "-" $exec $BRKNAME >>MessageFlows.txt
mqsichangetrace $BRKNAME -u -e $exec -l none -r
fi

#--------- Check whether the message flow under a perticular broker and execution group is in debug mode -----------
for flow in `mqsilist $BRKNAME -e $exec |awk '{print substr($3,0,50)}' |grep -v "command"`
do
flows=`expr $flows + 1`
flag=`mqsireporttrace $BRKNAME -u -e $exec -f $flow |grep -v "BIP8071I:" |awk '{print substr($4,0,5)}'`

if [[ $flag = debug ]]; then

mqsichangetrace $BRKNAME -u -e $exec -f $flow -l none -r
