I have a bunch of files that all follow the same pattern of data.

Let's say that this is the pattern i want to extract from:

`First part of text...patternA......Second part of text.....patternB.....Third part of text....patternC.....End part of text`

Currently i am using this:

`grep -P -o ".{0,5}patternA|.{0,5}patternB.{0,5}|patternC.{0,5}" filename.txt`

With this the output i am getting is :
 
 1111 patternA
 2222 patternB 2222
 patternC 3333

The output i actually want is :

`1111 patternA 2222 patternB 2222 patternC 3333`

I can't seem to figure out how to get rid of the newlines at the end of each pattern.

How can i accomplish this?
