Hi experts!
I want every 2nd and 3rd line in a file to be joined to the previous line using unix.
No perl commands please
EG: in my file:
Do
Not
Leave
Do
Take
Care

I need the output as:
Do Not Leave
Do Take Care

Plssssss help

Hi,

is awk OK?

awk 'NR%3==1 {str=$0}
NR%3==2 {str=str" "$0}
NR%3==0 {print str,$0}
END {if (NR%3) print str}' filename

This will even take care for incomplete fields at the end of a file.
