Cannot duplicate all ouput to a file with tar/pigz [duplicate]

  • 772

I'm using in my script:

tar cfh - "$SRC_DIR" --exclude-from <(find $SRC_DIR -size +$EXCLUDE_MB_FILES) | pigz -9 --quiet --keep --recursive --rsyncable > $BACKUP_TARGER_DIR/$ARC_NAME | tee $LOG_FILE

But LOG_FILE is empty. Why?

command-line

    Split command:

    find -L $SRC_DIR -size +$EXCLUDE_MB_FILES > $EXCLUDE_LIST 2>> $LOG_FILE
RC=$?;
if [[ $RC != 0 ]]; then
    error find $RC
fi

tar cfh $TAR_FILE "$SRC_DIR" --exclude-from $EXCLUDE_LIST &>> $LOG_FILE
RC=$?;
if [[ $RC != 0 ]]; then
    error tar $RC
fi

pigz -9 --quiet --keep --recursive --rsyncable $TAR_FILE &>> $LOG_FILE
RC=$?;
if [[ $RC != 0 ]] || [ ! -f $GZ_FILE ]; then
    error pigz $RC
fi

mv $GZ_FILE $BACKUP_TARGER_DIR/$ARC_NAME
RC=$?;
if [[ $RC != 0 ]]; then
    error mv $RC
fi
