The grep and sed you have in the script does not modify the file you wanted to or its not the correct way to do it. Try as
Code:
michaelf>cat fil.ksh
#!/bin/ksh

echo "Enter Old domain name:"
read old

echo "Enter New domain name:"
read new

sed "s/$old/$new/g" /home/michael/infile > /home/michael/tmp

#after verifying the results in the file /home/michael/tmp, uncomment the below line to rename to the original file name
#mv /home/michael/tmp /home/michael/infile
michaelf>

If your version of SED supports -i option then you could use it instead of mv command
Code:
sed -i "....

Worked
Smilie Problem was with quotes :
Code:
echo "Enter Old domain name:" 
read old  
echo "Enter New domain name:" 
read new  

grep -rl "$old" /var/www | xargs sed -i "s/$old/$new/g" 
exec bash
