Convert few columns to rows

Hi!
Does anybody help me in converting following data:

INPUT looks like this:
Code:
20. 100.        
30  200.
40. 400.
50. 100.        
60.  200.
70. 400.
80. 200.
150. 210.
30. 100.

OUTPUT should look like this:
Code:
20. 100.     30  200.   40. 400.    50. 100.        
60.  200.     70. 400.   80. 200.   150. 210.
30. 100.

Thanks a lot for your help!

Assuming your input is same as you have provided..

Code:
xargs -n 8 < file

Simplest what one can do is..

Code:
 
printf "%s %s %s %s %s %s %s %s\n" $(cat filename)

It works but I would like to have %8.2f for each value. Thanks!

Wonderful its very simple, In case if I have only 2 values left in the last row it is simply writing zeros in other 6 places. If I use a conditional statement qual to NF it will work.

Try this..
I know this is not the best way. you have to handle some spacing...Smilie

Code:
xargs -n 8 < file | awk '{if(! max){max=NF}{for(i=1;i<=max;i++){if($i == ""){ $i=0}}}}1'

first of all Thanks! unfortunately, I still have zeros at the end.

Here is the working script
Code:
awk 'BEGIN {
i = 1}
{
printf "%8.2e %8.2e ", $1,$2
i = i+1
if (i == 5)
{
i=1; printf "\n" 
}
}
END {
}' file
