get status of previous command

We may need to know the status of previous command sometimes. Whether this is successed or this is failed.According to teh situation we may need to perform some operation.So for this we need to understand whether our command ran successfully or not.
Here you go

nohup bash $Script_Path/scripts/Customer_Trans.sh
EXIT_STATUS=$?

Now the status is in EXIT_STATUS . This will be 0 if the process ran successfully.

if [ $EXIT_STATUS != 0 ]
then
echo "Automatic reconciliation process failedat : `date +%Y%m%d` ." | mailx -s "Monthly Reconcilation" $Mail_ID
else
echo "Automatic reconciliation process successfully  ended at : `date +%Y%m%d` ." | mailx -s "Monthly Reconcilation" $Mail_ID

fi

Hope this is clear to you .
