[SOLVED] How to insert a newline in front of a pattern?

Issue

How to insert a newline before a pattern within a line?

For example, this will insert a newline behind the regex pattern.

sed 's/regex/&\n/g'

How can I do the same but in front of the pattern?

Given this sample input file, the pattern to match on is the phone number.

some text (012)345-6789

Should become

some text
(012)345-6789

Solution

Some of the other answers didn't work for my version of sed. Switching the position of & and \n did work.

sed 's/regexp/\n&/g' 

Edit: This doesn't seem to work on OS X, unless you install gnu-sed.
