The sed command works as expected at the command prompt, but does not work in a shell script.

new_db_name=`echo "$new_db_name" | sed 's/$replace_string/$replace_with/'`

Why is that, and how can I fix it?

    Use double quotes for the sed expression.

    new_db_name=$(echo "$new_db_name" | sed "s/$replace_string/$replace_with/")
