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

doubt in using sed
I have made a script like this as test1
#!/bin/bash
line="3IINFOTECH,2005042200,118,118,96,98.1,8260440"
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
[EMAIL PROTECTED]:~/.qtstalker/data0/export$ test1
2005042200
20050422
3IINFOTECH,2005042200,118,118,96,98.1,8260440
3IINFOTECH,2005042200,118,118,96,98.1,8260440
I don't find any replacement. Where am I wrong? what should be done to get
the replacement done?
