Replace a string including a newline character 1

[neuralnode]

Hi All,

Here's the task:

The contents of a text file is like this:

this is a string
55 and some other text

I want to replace every occurence of a newline character and the string "55".
So whenever there is "55" starting a line, the preceding newline character should be replaced with a space.

How can I do that?
(with some regex in perl/sed/awk)

Thanx in advance!

One way with awk:
awk 'NR>1{if($1~/^55/)printf " ";else printf "\n"}{printf "%s",$0}END{printf "\n"}' /path/to/input

Hope This Helps, PH.
