@Rudi -

Thank you so much. I have to say, that was a complete oversight on my part! I copied that exit portion in wrong.

It should be:

Code:
exit 1
fi

As far as the trap command, I've put earlier in the script. Is that correct?

@bakunin -

Thank you for that explanation. If I followed it correctly, my script should look like the following:

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}
trap "[ -s ${_EF} ] || rm -f ${_EF} ] && rmdir ${_ARC_EF}"

#:: Begin Login Process --::
echo ----------------------------------------------------------
echo "Execute all command lines"
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
sh ${_EPM_SYSTEM_BIN}Utility.sh ${_IMPORTEXPORT_DIR}Export.xml

#:: Begin Error Check --::
echo ---------------------------------------------------------                                                                                                
echo "Check for command line errors"                                         
echo ---------------------------------------------------------

if ! "s/name=\"\" password=\"\"/name=\"${LCM_USER}\" password=\"${LCM_PSWD}\"/" ${_IMPORTEXPORT_DIR}Export.xml > ${_IMPORTEXPORT_DIR}Export1.xml ; then
     echo "Error adding ${LCM_USER} and ${LCM_PSWD} to Export.xml" >2&
     exit 4
fi

if ! rm ${_IMPORTEXPORT_DIR}Export.xml > ${_IMPORTEXPORT_DIR}Export1.xml ; then
     echo "Error removing Export.xml" >2&
     exit 3
fi

if ! mv ${_IMPORTEXPORT_DIR}Export1.xml ${_IMPORTEXPORT_DIR}Export.xml ; then
     echo "Error renaming Export1.xml to Export.xml" >2&
     exit 2
fi

if ! sh ${_EPM_SYSTEM_BIN}Utility.sh ${_IMPORTEXPORT_DIR}Export.xml ; then
     echo "Error executing LCM Backup for ${_LCM_DIR} " >2&
     exit 1
fi

exit 0

Is that correct?

Thank you, both!

As long as it's early enough to catch all the events it is intended for, yes. You are missing the trap events/signals in your new script, though.

Hi Rudi -

I guess im confused. Where would the trap command go then? After the command lines but before the exit portions?

Also, with the new script format, what happens when I'd only want the next command to execute only if the previous one is successful? With the new format, wont all commands execute regardless of return code?

Thanks!

Why not put the trap command in the script's second line right after the "shebang"? You need to get your head around it - it is not executing anything but setting a pointer to a command to be executed when the signals (in sigspec) occur any time during script execution.
And no - failing commands will make the script exit with the respective exit code.

More or less. In fact there are some syntactical errors like:
Code:
[...snip...]
if ! "s/name=\"\" password=\"\"/name=\"${LCM_USER}\" [...snip]

Where perhaps the initial command sed is missing, but i suppose that comes from copying. Otherwise you got it.
