Shell Programming and Scripting

Hi,

I've some files with the following data and i need to convert the lines between the separator ---, into a single line. I've tried with the paste cmd but my main problem is that the number of lines between the separator is not fix, it can vary between 1-4 lines.

Input

Code:

---
2010-02-22 12:25:32
191
---
2010-02-22 12:25:32
---

Output

Code:

--- , 2010-02-22 12:25:32 , 191
--- , 2010-02-22 12:25:32

Sometime ago i posted this message and got the following solution:

Code:

awk 'END{print _}/^-/{if(_)print _;_=$0;next}{_=_" , "$0}' infile

My problem is that this solution only works on Ubuntu 9.10 and i recently upgraded my machine to Ubuntu 10.04, and when i execute the awk command it only returns the last line before the separator (---).

Amy ideia why this happens?

Thanks in advance
