With the knowledge of the content of your files it is easier to
answer. Running the script in trace mode is the best thing to do.
Anyway, I see that there are two problems here (which may or may not
be related to your problem):

Where am I wrong
By the way, you might want to call your script as
bash -x scriptname
This will run the script in trace mode, much facilitating debugging.
You might also set PS4 to something sensible first. Personally, I
prefer PS4='+$0 l $LI

This syntax is broken. Any of these alternatives will work:
- let i=$i+1
- let i+=1
- i=$(( i + 1 ))
Basically, you need to let bash know that $i is an integer, and not a
string.

Your counter is wrong. $i + 1 means to treat i as a string and to
append the string "1" to it. If you want to do arithmetic in bash, you
have to put it in
I have a script as follows
[EMAIL PROTECTED]:~$ cat bin/getlstocks
#!/bin/bash
i=0
while [ $i -ne 20 ]
do
for trv in $(cat temp)
do
i=$i+1
grep $trv stock/nsedata/2008/05/20080512.txt >> lstock
done
done
when I run I get error as
