Text Manipulation/Replacement

[Ubence Quevedo]

Hello All,

I've used pdftotext to convert a pdf document to text and then used a
combination of grep and awk to single out data and replace formatting
that I didn't need.

The output data eventually looks like this:
12,123456789
,0987654321

But I want it to look like this:
12,123456789,0987654321

I've tried many different things with awk, but I can't get it replace \r, with just a ,

Does anyone have any ideas on how I can accomplish this, or at least give me an idea of what I'm doing wrong?

Thanx in advance for any help.
