Hi Folks -

Adjusted the code accordingly, however the directory is not being removed (Error file subdirectory).

Code:
#:: ------------------------------------------------------------------------
#source /u01/Hyperion_Batch/Scripts/Batch/_env.sh

#::-- Set Script Action --::#

_ACTION=Export

#::-- Set Script Name --::#
#::-- ${_SN%%.sh*} --::

_SN=${0##*/}

#::-- Set Path Variables --::

cd $HOME

_MAINPATH=$(pwd)/Hyperion_Batch/
_LOGPATH=Logs/
_ERRORPATH=Errors/

#::-- Set Log & Error subdirectories pertaining to the 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 STDOUT and STDERROR repositories --::
_ARC_LP=${_MAINPATH}${_LOGPATH}${_PLOGPATH}${_YEAR}_${_MONTH}${_DAY}
_ARC_EP=${_MAINPATH}${_ERRORPATH}${_PERRORPATH}${_YEAR}_${_MONTH}${_DAY}
    
mkdir -p ${_ARC_LP}
mkdir -p ${_ARC_EP}

#::-- Prepare File Name Format --::#
_HOST=$(hostname -f)
_FN=${_SN%%.sh*}_${_HOST}_${_TIME}

#::-- Establish STDOUT and STDERROR files --::#
_LF=${_ARC_LP}/${_FN}.log
_EF=${_ARC_EP}/${_FN}.err

#::-- Direct STDOUT and STDERROR to repositories --::# 
exec 2>${_EF} > ${_LF}

#::-- If empty, delete YYYY_MMDD error file subdirectory --::
trap "[ -s ${_EF} ] || rm -f ${_EF} ] && rmdir ${_ARC_EF}" EXIT

#::-- Establish LCM Variables --::

_EPM_SYSTEM_BIN=/u01/EPM/Oracle/Middleware/user_projects/epmsystem1/bin/
_IMPORTEXPORT_DIR=/u01/EPM/Oracle/Middleware/user_projects/epmsystem1/import_export/

  echo "${_LCM_DIR} Life Cycle Management Backup Unsuccessful"

  fi

Could there be a hidden file in the directory that I"m not seeing?

Thanks!

Is the log file actually empty?

The log file will never be empty. A log file is always generated upon execution, but not an error file.

Therefore, my script will build the following directories to direct standard output and stadnard error:

Code:
<Path>/Logs/LCM_Logs/2016_1216
<Path>/Errors/LCM_Errors/2016_1216



If <Path>/Errors/LCM_Errors/2016_1216 directory is empty (no error files generated, then delete 2016_1216.

I hope I was clear enough?

But is the error log actually empty? Look at it with ls -l . Zero bytes?

_ARC_EF is not defined in your script. And, there's a ] too many in your trap statement.

HI -

Yup, no error file is even generated.

---------- Post updated at 12:48 PM ---------- Previous update was at 12:45 PM ----------

Found the issue,

It should be
Code:
trap "[ -s ${_EF} ] || rm -f ${_EF} ] && rmdir ${_ARC_EP}" EXIT

I changed _ARC_EF to -ARC_EP. My fault! Thank you all for your help! Sorry for the bother!

You still have the extra ] in there, rm -f ${_EF} ] should be rm -f ${_EF}
