Executing multiple child scripts - failing

Hi Folks -

Happy Thursday!

I have a need where I have Parent/Control script that calls multiple child scripts. The problem is, after the first child script is executed, it fails to move to the next script. I assume it's due to my script exit?

For instance, in batch to return to the parent process, you exit with the following command:

Code:
exit /b <insertexitcodehere>

Is there something simlar in shell?

Here is my code:

Code:
source /u01/app/Hyperion_Batch/Scripts/Shell/_env.sh

#::-- Set Script Name --::
_SN=${0##*/}

echo "Script Name: $_SN"
echo "Script Name without EXT: ${_SN%%.sh*}"

#::-- Set Path Variables --::
_MAINPATH=/u01/app/Hyperion_Batch/
_LOGPATH=Logs/
_ERRORPATH=Errors/

#::-- Set Log & Error subdirectory pertaining to specific process --::

_PLOGPATH=LCM_Logs/
_PERRORPATH=LCM_Errors/

#::-- Set Date and Time Variable --::
_DAY=$(date +%d)
_MONTH=$(date +%m)
_YEAR=$(date +%Y)
_DATESTAMP=${_YEAR}${_MONTH}${_DAY}
_HOUR=$(date +%H)
_MINUTE=$(date +%M)
_SECOND=$(date +%S)
_TIME=${_HOUR}${_MINUTE}
_DATETIMESTAMP=${_DATESTAMP}_${_TIME}

#::-- Establish Log and Error File Directories --::
_ARC_LF=${_MAINPATH}${_LOGPATH}${_PLOGPATH}${_YEAR}_${_MONTH}${_DAY}
_ARC_EF=${_MAINPATH}${_ERRORPATH}${_PERRORPATH}${_YEAR}_${_MONTH}${_DAY}
    mkdir -p ${_ARC_LF}
    mkdir -p ${_ARC_EF}

#::-- Prepare File Name Format --::    
_FN=${_TIME}_${_SN%%.sh*}

#::-- Establish standard out and standard error --:: 
_LF=${_ARC_LF}/${_FN}.log
_EF=${_ARC_EF}/${_FN}.err

#::-- Establish LCM Specifics --::

_EPM_SYSTEM_BIN=/u01/app/Oracle/Middleware/user_projects/epmsystem1/bin/
_IMPORTEXPORT_DIR=/u01/app/Oracle/Middleware/user_projects/epmsystem1/import_export/TVeriRep_Automation_Base/
_LCM_DIR=ESB-TVerRep


exec 2>${_EF} > ${_LF}

#:: Begin Script Processing --::
echo ----------------------------------------------------------
echo "Add $LCM_USER & ${LCM_PSWD} to Export XML ..."
echo ----------------------------------------------------------

sed "s/name=\"\" password=\"\"/name=\"${LCM_USER}\" password=\"${LCM_PSWD}\"/" ${_IMPORTEXPORT_DIR}Export.xml > ${_IMPORTEXPORT_DIR}Export1.xml
rm ${_IMPORTEXPORT_DIR}Export.xml
mv ${_IMPORTEXPORT_DIR}Export1.xml ${_IMPORTEXPORT_DIR}Export.xml


echo ---------------------------------------------------------                                                                                                    
echo "Execute ${_LCM_DIR} Life Cycle Management Backup"                                         
echo ---------------------------------------------------------

sh ${_EPM_SYSTEM_BIN}Utility.sh ${_IMPORTEXPORT_DIR}Export.xml

if [ $? -eq 0 ]
then
  echo ---------------------------------------------------------
  echo "${_LCM_DIR} Life Cycle Management Backup Successful"                           
  echo ---------------------------------------------------------
  #::-- If empty, delete YYYY_MMDD error file subdirectory --::
  trap "[ -s ${_EF} ] || rm -f ${_EF} ] && rmdir ${_ARC_EF}" EXIT 0
  
else
  echo ---------------------------------------------------------
  echo "${_LCM_DIR} Life Cycle Management Backup Unsuccessful"                      
  echo ---------------------------------------------------------
  fi
  exit 1

Thanks!

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
