can somebody pls help me understand what is happening here in lines started with headingcopy, linecopy, and sed, don’t fully understand what these headingcopy or linecopy mean as I don’t recognize these commands and, if they are variables, where are they used?… 

GetReportParams|grep -iv conn|grep -v "^$"|while read DB_SCHEMA REP_IDX ORG_SHORT_NAME SQL_SCRIPT OUTPUT_FILE_NAME REPORT_NAME REPORT_TYPE OUT_FILE_EXT ORG_NAME MAIN_EMAIL BCC_EMAIL REPORT_GROUP PARAMETERS

  echo Running report for -- $PARAMETERS
  # Remove text qualifier character

  HeadingCopy=`head -1 $OUTDIR_main/$MAIN_FILE_NAME | tee -a ${OUTDIR_main}/${TMP_FILE_NAME} `
  LineCopy=`grep ^"$PARAMETERSSEARCH" $OUTDIR_main/$MAIN_FILE_NAME | tee -a ${OUTDIR_main}/${TMP_FILE_NAME} ` 
  sed 's/[ \t]*$//' ${OUTDIR_main}/${TMP_FILE_NAME} > ${OUTDIR}/${OUTPUT_FILE_NAME}
  sed -i 's/[^,]*,//' ${OUTDIR}/${OUTPUT_FILE_NAME}
  #cat ${OUTDIR}/${OUTPUT_FILE_NAME}

    HeadingCopy=`head -1 $OUTDIR_main/$MAIN_FILE_NAME | tee -a ${OUTDIR_main}/${TMP_FILE_NAME} `

    copies the first line from the file $OUTDIR_main/$MAIN_FILE_NAME to the variable HeadingCopy and also redirects(appends) the output to a file ${OUTDIR_main}/${TMP_FILE_NAME}

     LineCopy=`grep ^"$PARAMETERSSEARCH" $OUTDIR_main/$MAIN_FILE_NAME | tee -a ${OUTDIR_main}/${TMP_FILE_NAME} `

    copies the line which start with the string that is present in the variable PARAMETERSSEARCH and
    also redirects(appends) the output to a file ${OUTDIR_main}/${TMP_FILE_NAME}

    second sed will replacs every line the data in the file from the first character till it encounters a “,”
