Print awk output on the same line

How do I print awk output on the same line.

I am using this to print the resolution of my monitor:

$ xrandr | awk '/\*/{print $1}'

When I connect a second monitor I get output on two lines, 

$ xrandr | awk '/\*/{print $1}'

1920x1200
1600x1050

I would like to have the output on the same line. So it will look like this:

Monitor sizes: 1920x1200 1600x1050

How would I do this the simplest way?

Solution

  • I have found this solution that is similar to what anubhava posted.

        $ xrandr | awk '/\*/{printf $1" "}'
    1920x1200 1600x1050
