It could be simplified by using:-
Code:
while read acc
do
   bip.sh $acc
done < sql_output.txt

This will loop for every record in your file. Be careful if you need to exclude things such as the column headings and numbers of row returned or blank lines.

If you have more than one column in the file and (for instance) the account number is in column 2 and you don't care about columns 1, 2 or three and from 5 onward, you could:-
Code:
while read col1 col2 col3 acc rest
do
   bip.sh $acc
done < sql_output.txt


You could run bip.sh 01 $acc if the 01 is a required parameter or even bip.sh 01 $acc & to run it in the background, but be careful if your file may have more than just a few records. There are limits to how many processes you should have running at the same time.



I hope that this helps
