Combine lines from file

Hello,

Input file looks like this:
apples
bananas
oranges and rice
pears
cherries
mango

I want output to look like this:
apples bananas
oranges and rice pears
cherries mango

It should combine line 1 with line 2 and line 3 with line 4 like that....

Right now, only way I can think is to use head -n 2 but I want output file to be created with all of input processed....

Thanks for all the help in advance!!!

This is a very basic start, i'm sure something much more elegant could be done with awk Smilie

Code:
#!/bin/bash

FILE="/tmp/file.txt"
COUNT=1

for i in `cat ${FILE}`
do
	if [ "$((${COUNT}%2))" -eq 1 ]
	then	
		echo -n "${i}"
	else
		echo " ${i}"
	fi	

	let COUNT=$COUNT+1
done

With awk:
Code:
awk '{ORS=(NR%2)?FS:RS}1' infile

and with sed:
Code:
sed 'N;s/\n/ /' infile
