Hi, I tried the way mentioned above and removed exit command from the script, it still gives comes with exit code 0 and the execution processes further:

Code:

ssh -i /opt/apps/lib/keys/nfs_appsadm_key $apps_USER@$SOURCE_MACHINE_NAME <<EOF 
sleep 2 
echo $SOURCE_SW_NAME 
sleep 2 
sudo su - $SOURCE_SW_USER <<su_EOF 
  
        /opt/apps/home/apps/scripts/procedure_export.sh -t $TICKET_NUMBER -f $PROCEDURE_LIST_FILE 
 
su_EOF 
EOF 
sleep 2 
echo $? 
echo Export of source procedures complete  | tee  -a $BATCH_PROMO_LOG

Here's the log of above utility:

Info May 9, 2013 10:06:43 PM [stdout: 2] Parsing input file /opt/apps/home/apps/bladelogic_scripts/procedure_name.txt for duplicate values at first column
2
Info May 9, 2013 10:06:44 PM [stdout: 2] ####Error - Duplicate procedure entries exists in the /opt/apps/home/apps/scripts/procedure_name.txt, please remove duplicate values from input file, exiting now.#### avikal is duplicate
2
Info May 9, 2013 10:06:46 PM [stdout: 2] 0
2
Info May 9, 2013 10:06:46 PM [stdout: 2] Export of source procedures complete
2

The OS is solaris, and my used case is to parse the file for duplicate values at column first in export script, if they exists execution should stop completely.

Please advise.

Nevermind guys, sleep before catching the exception was the issue. Script is now working as expected. Apologies and thanks for the inputs.

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.	If you link to this script with a hostname then executing the link is
