I have a file with name input_file.spec.

This file has records like:


Record #: 1

rec_len = 590
rec_id = 31229
filler_4 = " "
orig_id = 902162988
seqnum = 138960799
lrnid = "0"
l_ind = "0"
transaction_cnt = 1
cust_id = 61032336
product_id = 135488621

ans so on.

It has 1000 records in this file.

I have to give new numbering to seqnum field only.
i am gogin to start with 1 and ll end with 1000.

I worte this:

#!/bin/ksh
i=1
echo "Give input file"
INPUTFILES=input_file.spec
cat $INPUTFILES | while read LINE
do
let i=i+1
sed -e '/seqnum/s/seqnum = [0-9]*/seqnum = '$i'/g' $LINE
done


but the "i" is not getting interpolated event when its reading line by line.

Can u please tell any option in unix to do the same.
or alternative to do the same business.

Try this:

Sorry i didnt wrk as per my requirements.
Can u please lookin the sed only?

Thanks and Regards,

in your sed command, try replacing single quotes with double quotes

and you have to take care of escaping (characters such as < " * etc) then
