I have made a script like this as test1
#!/bin/bash
line="3IINFOTECH,20050422000000,118,118,96,98.1,82 60440"
olds=$(echo "$line"|cut -d, -f2)
echo $olds
da=${olds:0:8}
echo $da
echo "$line" > temp1
sed -e 's/$olds/$da/' temp1 >>temp
cat temp1
cat temp
When I run get as
lvgandhi@lvgdell600m:~/.qtstalker/data0/export$ test1
20050422000000
20050422
3IINFOTECH,20050422000000,118,118,96,98.1,8260440
3IINFOTECH,20050422000000,118,118,96,98.1,8260440
I don't find any replacement. Where am I wrong? what should be done to get
the replacement done?

You want to use double quotes here so that the shell can expand the variables.

The problem is that you've used single quotes, preventing shell
expansion of your variables. Try:

sed -e "s/$olds/$da/" temp1 >>temp

My guess is that will work for you.

You forgot a 's': 'datafiles' vs. 'datafile'.
