KSH для динамического создания n строк для таблицы: проблема с оператором if else

Мне нужно сгенерировать миллиард записей в текстовом файле для загрузки таблицы.

Мое определение целевой таблицы:

CREATE  TABLE txnrecords12(
  txnno int, 
  txndate string, 
  custno int, 
  amount double, 
  category string, 
  product string, 
  city string, 
  state string, 
  spendby string)
ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY ',' 

Для генерации данных мой код:

############!/bin/sh
####### Create file dynamically
 if [ ! -d hero_work ]
then
    mkdir hero_work
fi
TEMPDIR=$HOME/hero_work
cd $TEMPDIR
touch $TEMPDIR/big_data_file_$$
echo $"string1\n",printf "string1\n",printf "string1\n">>big_data_file_$$

Когда я запускаю код, я получаю следующую ошибку каждый раз
