Error While loop read line Issue
Hi

I am using while loop, below, to read lines from a very large file, around 400,000 rows. The script works fine until around line 300k but then starts giving incorrect result.

I have tried running the script with a smaller data set and it works fine. I made sure to include the line where the problem starts in the data set to make sure there are no special characters that are causing the issue.

Please let me know if this is a script issue or some size limit issue.

Code:
while read line
do
count=0
echo $line | cut -c250-310  | cut -d"_" -f3 | cut -c1-9 | sed 's/ //g' | read tran_id
echo $line | awk '{ n += gsub( "<TCRMContractPartyRoleBObj>", "") } END { print n }' | sed 's/ //g' | read count
count=$n
echo $tran_id"|"$count >> $XML_OUTPUT
done < $XML_INPUT_FILE

Output - Problem starts at line 386501 below and continues till end of file
Code:
+386498 TK1251683|1
+386499 TK1251684|2
+386500 TK1251684|4
+386501 nNameBObj|1
+386502 hodBObj><|1
+386503 e><XSpoke|1
+386504 tractType|1
+386505 ourceIden|1
+386506 ountryTyp|1

Thanks
Saurabh

I see so many pipes in your code, and many are useless.

Provide some sample inputs for us to thin your code.

First, i would quote $line in lines 4 and 5
Code:
echo "$line" | cut -c250-310  | cut -d"_" -f3 | cut -c1-9 | sed 's/ //g' | read tran_id
echo "$line" | awk '{ n += gsub( "<TCRMContractPartyRoleBObj>", "") } END { print n }' | sed 's/ //g' | read count

But sure there are better ways, as wrote rdcwayx above...
