sed script- current and next line

Hi

I have been using
Code:
sed -n -e '/regex/{N;p;}'

to print the matching line and the next line.

In cases where I have a matching line at the end of the document with no next line, that line is skipped. How do I print that line as well?

Thanks.

Perfect! Thanks.

Any ways to print without the -- between records?

A thought - what about matches on consecutive lines?
e.g.
Code:
# cat x.txt
a
regex 1
b
c
regex 2
regex 3
d
e
regex 4
