Thanks. I will not use the -E flag then.

You are right. My mistake. This indeed works:
sed -E -e "s/^[0-9]+/199/" conf-split > conf-split.new
Thanks for clearing this up.
For what it's worth, there is another way to write this regexp without
using the -E flag. Since x+ == xx*, you can write it:
"s/^[0-9][0-9]*/199/". The reason for not using -E is that it's not
portable, since it's not specified by the standard. GNU sed uses -r for
extended REs.
Cheers,
